Question

by what number should (-35)-1 be divided so that the quotient is may be 7-1​

Answer 1

Step-by-step explanation:

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 x 1/x = 1/-5

Or, 1/15x = 1/-5

Or, x = -5/15 Or, x = -1/3.

Hence the required number is -1/3
