### By what number do you divide 10 by to get -2?

• A.

-8

-5

• C.

5

• D.

Explanation
To find the number by which 10 should be divided to get -2, we can use the formula: dividend ÷ divisor = quotient. In this case, the dividend is 10 and the quotient is -2. Rearranging the formula, we get: divisor = dividend ÷ quotient. Therefore, the divisor is 10 ÷ -2, which equals -5. Hence, the correct answer is -5.
