### -24/6 =    (/ means division)

• A.

4

• B.

-4

• C.

6

B. -4
Explanation
When dividing -24 by 6, the result is -4. This is because when dividing two numbers with different signs, the result will have the sign of the number with the higher absolute value. In this case, -24 has a higher absolute value than 6, so the result is negative.

### -2 x 4 x -6        (x means multiply)

• A.

-4

• B.

-48

• C.

### -6 + 12 - 3

• A.

3

• B.

9

• C.

21

A. 3
Explanation
The given expression is -6 + 12 - 3. To solve this expression, we start from left to right. First, we add -6 and 12, which gives us 6. Then, we subtract 3 from 6, resulting in 3. Therefore, the correct answer is 3.

### -2 x -16 x -4           (x means multiply)

• A.

128

• B.

-128

• C.

-22

B. -128
Explanation
When multiplying three negative numbers (-2, -16, -4), the result will be negative. The product of -2 and -16 is 32, and then multiplying that by -4 gives us -128. Therefore, the correct answer is -128.

Rate this question:

• 8.

### (12/-4) + (-64/8) =           (/ means to divide)

• A.

11

• B.

-11

• C.

-5

B. -11
Explanation
The given expression involves adding two fractions. To add fractions, we need to have a common denominator. In this case, the common denominator is 8. So, we convert the first fraction (12/-4) to an equivalent fraction with a denominator of 8 by multiplying the numerator and denominator by 2. This gives us -24/8. Then, we add the two fractions: (-24/8) + (-64/8) = -88/8. Simplifying this fraction, we get -11. Therefore, the correct answer is -11.

Rate this question:

• 9.

### (-63/-7) + (-15/15)

• A.

-10

• B.

8

• C.

-8

B. 8
Explanation
The given expression involves the addition of two fractions: (-63/-7) and (-15/15). When we simplify each fraction separately, we find that (-63/-7) equals to 9 and (-15/15) equals to -1. Adding these two fractions together, we get 9 + (-1) = 8. Therefore, the correct answer is 8.

Rate this question:

• 10.

### 42/-6     +      -150/3

• A.

-57

• B.

43

• C.

-43

A. -57
Explanation
The given expression involves adding two fractions, 42/-6 and -150/3. To add fractions, we need to have a common denominator. In this case, the common denominator is 6. After finding the common denominator, we can add the numerators. The numerator of the first fraction is -42, and the numerator of the second fraction is -150. Adding these gives us -192. Therefore, the sum of the two fractions is -192/6, which simplifies to -32. Therefore, the answer is -32.
