### SOLUCIONE:45/6 + 31/3 + 21/2 =

Explanation
The given expression is a sum of three fractions. To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 6. We then convert each fraction to have a denominator of 6.

45/6 is already in terms of 6, so it remains the same.

31/3 can be converted to 62/6 by multiplying the numerator and denominator by 2.

21/2 can be converted to 63/6 by multiplying the numerator and denominator by 3.

Now that all fractions have a common denominator of 6, we can add them together.

45/6 + 62/6 + 63/6 = 170/6 = 28 2/6 = 28 1/3 = 10 2/3.

Rate this question:

Rate this question:

• 24.

### SOLUCIONE:2/3 = ___ /12

Explanation
The given equation is asking to find the equivalent fraction to 2/3 when the denominator is 12. To solve this, we need to find the number that when multiplied by 3 gives 12. This number is 4. So, if we multiply the numerator 2 by 4, we get 8. Therefore, the equivalent fraction to 2/3 when the denominator is 12 is 8/12.

Rate this question:

• 25.

### SOLUCIONE:5 - 11/3 =

Explanation
The given expression is 5 - 11/3. To subtract a whole number from a fraction, we need to convert the whole number into a fraction with the same denominator as the fraction. So, 5 can be written as 15/3. Now, we can subtract the fractions: 15/3 - 11/3 = (15 - 11)/3 = 4/3. The result is an improper fraction, which can be simplified to a mixed number: 4/3 = 1 1/3. Therefore, the correct answer is 3 2/3.

Rate this question:

• 26.

### SOLUCIONE:¾ año = ____ meses

Rate this question:

• 27.

### SOLUCIONE:2 1/3 docenas = _______

Explanation
The given question is asking for the value of 2 1/3 dozens. A dozen is equal to 12, so 2 dozens would be equal to 24. Adding 1/3 of a dozen to this would be equivalent to adding 1/3 of 12, which is 4. Therefore, 2 1/3 dozens would be equal to 24 + 4, which is 28.

Rate this question:

• 28.

### SOLUCIONE:7.96 x 30.8 =

Explanation
The given expression is a multiplication problem, where 7.96 is being multiplied by 30.8. By multiplying these two numbers, we get the product of 245.168.

Rate this question:

• 29.

### ¿Cuál de estas expresiones es mayor? ¿7/8 ó 13/15?

Explanation
The fraction 7/8 is greater than 13/15. This can be determined by finding a common denominator for both fractions and comparing the numerators. In this case, the common denominator is 120. When the fractions are converted to have this denominator, 7/8 becomes 105/120 and 13/15 becomes 104/120. Since 105 is greater than 104, 7/8 is the larger expression.

Rate this question:

• 30.

### Descubra el promedio de: 24, 18, 21, 26, 17 =

Explanation
The given answer, 21.2, 21 R 1, represents the average of the numbers 24, 18, 21, 26, and 17. To find the average, you add up all the numbers and then divide the sum by the total number of values. In this case, the sum of the numbers is 106 (24 + 18 + 21 + 26 + 17) and there are 5 values. Dividing 106 by 5 gives us 21.2. The "21 R 1" indicates that the average is 21 with a remainder of 1, meaning that the average is slightly above 21.

Rate this question:

• 31.

### Escriba en porcentaje: ¾ = _____ %

Explanation
The given question asks for the percentage equivalent of the fraction ¾. The fraction ¾ represents three-fourths, which means that three out of four equal parts are being considered. To convert this fraction into a percentage, we need to multiply it by 100. Therefore, ¾ is equal to 75%.

Rate this question:

• 32.

### SOLUCIONE41/5 x 31/3 =

Explanation
The given expression is a multiplication of two fractions: 41/5 and 31/3. To multiply fractions, we multiply the numerators together and the denominators together. So, multiplying 41 and 31 gives us 1271 as the numerator, and multiplying 5 and 3 gives us 15 as the denominator. Therefore, the result of the multiplication is 1271/15. However, the given answer is 14, which is incorrect.

Rate this question:

• 33.

### SOLUCIONE:3/10 ÷ 3/4 =

Explanation
When dividing fractions, we can multiply the first fraction by the reciprocal of the second fraction. In this case, we have 3/10 divided by 3/4. To find the reciprocal of 3/4, we flip the fraction, resulting in 4/3. Now we can multiply 3/10 by 4/3. Multiplying the numerators gives us 12, and multiplying the denominators gives us 30. Therefore, 3/10 divided by 3/4 is equal to 12/30. Simplifying this fraction gives us 2/5.

Rate this question:

• 34.

### SOLUCIONE:8/9 x 9/4 x 1/2 =

Explanation
The given expression is a multiplication of fractions. To solve it, we multiply the numerators together and the denominators together. The numerator becomes 8 x 9 x 1, which equals 72. The denominator becomes 9 x 4 x 2, which equals 72. Therefore, the fraction simplifies to 72/72, which is equal to 1.

Rate this question:

• 35.

### Escriba en decimal: 2/3 = ________
