Nilai dari 40 + ( - 7 ) = ....
- A.
47
- B.
- 47
- C.
- 33
- D.
33
Correct Answer
D. 33Explanation
When we add a positive number to a negative number, we subtract the absolute value of the negative number from the positive number. In this case, we have 40 as a positive number and -7 as a negative number. The absolute value of -7 is 7. So, when we subtract 7 from 40, we get 33. Therefore, the correct answer is 33.Rate this question:

- D.
100
Correct Answer
C. - 100Explanation
In order to find the missing number in the equation, we can work backwards from the given answer. Starting with the answer of -100, if we add 100 to it, we get 0. If we then subtract 50 from 0, we get -50. Continuing in the same manner, if we subtract 50 from -50, we get -100. Therefore, the missing number in the equation is -100.Rate this question:

Correct Answer
C. 1⁄10Explanation
The given options are fractions, and we are asked to identify the smallest fraction among them. To compare fractions, we need to find a common denominator. In this case, the common denominator is 60. When we convert the fractions to have a denominator of 60, we get 20/60, 15/60, 6/60, and 12/60. Among these fractions, 6/60 or 1/10 is the smallest fraction.Rate this question:

The correct answer is 1⁄25 , 1⁄10 , 1⁄8 , 1⁄2. This is the correct order of the given fractions from smallest to largest. The fraction 1⁄25 is the smallest because the denominator is the largest among all the fractions. Then, the fraction 1⁄10 comes next because its denominator is larger than 1⁄8. Finally, the fraction 1⁄2 is the largest because its denominator is the smallest among all the fractions.Rate this question:

- D.
3⁄15
Correct Answer
A. 7⁄15Explanation
The correct answer is 7/15. To find this answer, we need to subtract 1/3 from 4/5. To subtract fractions, we need a common denominator. In this case, the common denominator is 15. So, we convert 4/5 to 12/15 and subtract 1/3 from it. 12/15 - 5/15 = 7/15. Therefore, the answer is 7/15.Rate this question:

- C.
23⁄30
- D.
23⁄28
Correct Answer
A. 23⁄15Explanation
The given expression involves adding and subtracting fractions. To solve it, we need to find a common denominator for all the fractions involved. In this case, the common denominator is 30.
Converting each fraction to have a denominator of 30, we get:
25/30 + 1/3 - 2/5 = 25/30 + 10/30 - 12/30
Combining the numerators, we have:
25 + 10 - 12 = 23
Therefore, the final answer is 23/30.Rate this question:

Segitiga
- B.
Segiempat
- C.
Trapesium

Persegi panjang
Correct Answer
B. SegiempatExplanation
A segiempat (rectangle or square) is a shape that has four sides of equal length and four right angles. It is also a shape that has two lines of symmetry, one vertical and one horizontal, which means that if you fold the shape along these lines, both halves will match perfectly. Therefore, a segiempat is a shape that has four-fold rotational symmetry, making it the correct answer for the question.Rate this question:

Correct Answer
D. 1Explanation
The given answer is 1. This is because a kite has one line of symmetry. A line of symmetry is a line that divides a shape into two equal halves, where each half is a mirror image of the other. In the case of a kite, there is only one line that can be drawn to divide it into two equal halves. Therefore, the number of lines of symmetry in a kite is 1.Rate this question:

D. 2Explanation
A rectangle has two lines of symmetry, one vertically and one horizontally. This means that if you were to fold the rectangle along either of these lines, the two halves would perfectly overlap each other. Therefore, a rectangle has two lines of symmetry, which is the same as saying it has two rotations of symmetry.Rate this question:
