Question

Evaluate the expression.
1/7 divided by 2/5 - 1/7

Answer 1

The first thing that we should do is turn this into a mathematical formula.

`(1)/(7) / ((2)/(5) -(1)/(7) ) = (1)/(7) /((9)/(35) )` .

This is more generally written as

`7((9)/(35)) = (9)/(5)`

So, our answer is 9/5 or 1.8

Answer 2

3/14

Explanation:

In order to divide fractions, you'll have to find the recriprocal of 2/5. That is 5/2. So do 1/7 x 5/2 = 5/14.

So now find 5/14 - 1/7.

1/7 converted to a denominator of 14 is 2/14.

So we have 5/14-2/14 = 3/14. That is your answer.
