Question

By what number should −420 be divided to obtain 15?

• A. -28
• B. 28
• C. 25
• D. -25

Answer 1

The correct option is A -28

Here,
Suppose "a" divides −420 to obtain 15. Then, we have:

15 = $\frac{-420}{a}$ ,

a = $\frac{-420}{15}$,

a = -28

Hence, −420 should be divided by -28 to obtain 15.
