Question

by what number should
$(15) ^{ - 1}$
be divided so that the quotient may be equal to
$( - 5) ^{ - 1}$
​

Answer 1

Answer:

Let the number be x.

We know that, 15^(-1) = 1/15. and (-5)^(-1) = -1/5.

According to the question, (1/15)÷x = -1/5

Or, 1/15 × 1/x = 1/-5

Or, 1/15x = 1/-5

Or, x = -5/15

Or, x = -1/3.
