Soal Matematika Kelas 5 Sd Bab 6 Pecahan

When subtracting fractions, we need to have a common denominator. In this case, the fractions already have a common denominator of 15.

So, we can subtract the numerators directly: 9/15 - 3/15 - 4/15 = (9 - 3 - 4)/15 = 2/15.

Therefore, the result of the subtraction operation is 2/15.

The fraction 2/5 can be converted to a percentage by multiplying it by 100. When we multiply 2/5 by 100, we get 40%. Therefore, the correct answer is 40%.

The given question asks to subtract two fractions, 3/4 and 2/5. To subtract fractions, we need to have a common denominator. In this case, the common denominator is 20. So, we convert 3/4 to 15/20 and 2/5 to 8/20. Subtracting these fractions gives us 15/20 - 8/20 = 7/20. Therefore, the correct answer is 7/20.

Andi memiliki tali sepanjang 1/4 meter dan Ali memiliki tali sepanjang 1/3 meter. Untuk menjumlahkan panjang tali Andi dan Ali, kita perlu menemukan persamaan pecahan dengan penyebut yang sama. Kita dapat melakukannya dengan mengalikan penyebut dari masing-masing pecahan. Jika kita mengalikan 1/4 dengan 3/3, maka kita akan mendapatkan 3/12. Jika kita mengalikan 1/3 dengan 4/4, maka kita akan mendapatkan 4/12. Jadi, jumlah tali Andi dan Ali adalah 3/12 + 4/12 = 7/12.

The given question asks to add three fractions with a common denominator of 10. When we add the numerators (2+4+3) and keep the denominator the same, we get 9/10 as the result. Therefore, the correct answer is 9/10.

The correct answer is 0.75 because when you divide 3 by 4, the result is 0.75. This can also be represented as 75/100 or 75%.

The given question asks for the sum of two fractions, 1/2 and 3/8. To find the sum of fractions, we need to have a common denominator. In this case, the common denominator is 8. So, we convert 1/2 to 4/8 and add it to 3/8. The sum of 4/8 and 3/8 is 7/8. Therefore, the correct answer is 7/8.

The fraction 1/4 is equivalent to 25% when expressed as a common fraction. This is because 25% can be written as 25/100, which can be simplified to 1/4 by dividing both the numerator and denominator by their greatest common divisor, which is 25. Therefore, the correct answer is 1/4.

The correct answer is "

The correct answer is 30⁄100 because when converting a decimal to a fraction, the decimal part is written as the numerator and the place value of the decimal is written as the denominator. In this case, 0.30 can be written as 30⁄100.

When multiplying fractions, you simply multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator. In this case, 7/8 multiplied by 3/4 equals (7*3)/(8*4) which simplifies to 21/32. However, since the answer choices are given in the form of simplified fractions, we can further simplify 21/32 by dividing both the numerator and denominator by their greatest common divisor, which is 3. Therefore, 21/32 simplifies to 7/8, which matches the given answer of 21/24.

The given fractions are 4/5 and 7/10. To compare these fractions, we need to find a common denominator. The common denominator of 5 and 10 is 10. When we convert 4/5 to have a denominator of 10, we get 8/10. Now we can compare 8/10 and 7/10. Since 8/10 is greater than 7/10, the correct symbol to fill in the blanks is >.

Given that the ratio of male to female students in the class is 5:7, and there are 15 male students, we can calculate the number of female students by setting up a proportion.

Let x represent the number of female students.

We can set up the proportion:

5/7 = 15/x

Cross-multiplying, we get:

5x = 7 * 15

Simplifying, we have:

5x = 105

Dividing both sides by 5, we find:

x = 21

Therefore, the number of female students in the class is 21.

Diska awalnya memiliki pita sepanjang 1/2 meter. Kemudian ia menggunakan pita sepanjang 3/10 meter. Untuk mencari sisa pita Diska, kita perlu mengurangi panjang pita yang digunakan dari panjang pita awal. Jadi, sisa pita Diska adalah 1/2 - 3/10 = 5/10 - 3/10 = 2/10. Oleh karena itu, jawaban yang benar adalah 2/10.

The correct answer is 1:3 because the ratio of the number of pencils Sinta has to the number of pencils Rini has is 1:3. Sinta has 7 pencils and Rini has 21 pencils, which can be simplified to 1:3 by dividing both numbers by 7.

To find 25% of 120, we can multiply 120 by 0.25. This gives us 30, which is the correct answer.

The ratio between the number of male students and female students in the class is 4:7. This can be determined by dividing the number of male students (12) by the number of female students (21). Simplifying the ratio gives us 4:7.

The fraction 10/20 is not equivalent to 10% because to convert a fraction to a percentage, you need to divide the numerator by the denominator and multiply by 100. In this case, 10 divided by 20 is 0.5, and when multiplied by 100, it becomes 50%. Therefore, 10/20 is not equal to 10%.

Budi received the most oranges because he received 0.5 kg of oranges, while Santi received 10% of the oranges and Sinta received 3/10 kg of the oranges. Since 0.5 kg is a larger amount than 10% or 3/10 kg, Budi received the most oranges.

The given options are all numeric values. However, when comparing them to the number 32/1000, it can be observed that 32/1000 is the smallest value among all the options. Therefore, it is not equivalent to the other options.

The correct answer is 1 : 500. This is because the scale of the map is determined by the ratio of the distance on the map to the actual distance on the ground. In this case, 3 cm on the map represents 1500 meters in reality. To find the scale, we divide the actual distance by the distance on the map: 1500 meters / 3 cm = 500. Therefore, the scale of the map is 1 : 500.

The correct answer is 1/50. When we have a fraction, the denominator represents the total number of equal parts into which the whole is divided, and the numerator represents the number of those equal parts that we have. In this case, the whole is 0.02, and we need to find a fraction that represents a part of it. 1/50 means that we have 1 out of 50 equal parts of 0.02.

The distance between city X and Z on the map is 8 cm. The scale of the map is 1:200,000. This means that 1 cm on the map represents 200,000 cm in real life. To find the actual distance between the two cities, we need to multiply the distance on the map by the scale factor. Therefore, 8 cm x 200,000 cm = 1,600,000 cm. Since we want the answer in kilometers, we need to convert cm to km by dividing by 100,000. Therefore, 1,600,000 cm / 100,000 = 16 km.

The scale of the map is 1:40,000, which means that 1 cm on the map represents 40,000 cm in reality. Since the distance between Nabila's house and Siska's house is 800 meters, we need to convert this distance to centimeters. 800 meters is equal to 80,000 centimeters. Since 1 cm on the map represents 40,000 cm in reality, 80,000 cm will be represented by 2 cm on the map. Therefore, the correct answer is 2 cm.

The given question asks for the result of dividing the fraction 3/10 by the fraction 1/3. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/3 is 3/1. So, we can rewrite the division as 3/10 multiplied by 3/1. Multiplying the numerators (3 * 3) gives 9, and multiplying the denominators (10 * 1) gives 10. Therefore, the result of the division is 9/10.
