2 × 1/7 -1 2/5
Give your answer in its simplest form.​

Answer 1

the simplest form of the given expression is
`-1(4)/(35)`

Explanation:

Given;

`2 * (1)/(7) - 1(2)/(5)`

The above expression can be simplified as follows;

`2 * (1)/(7) - 1(2)/(5) \\\\=(2)/(7) - (7)/(5) \\\\= l.c.m \ of \ 7 \ and \ 5 \ is \ 35\\\\= (5(2) - 7(7))/(35) \\\\= (10 - 49)/(35) \\\\= -(39)/(35) \\\\= - 1(4)/(35)`

Therefore, the simplest form of the given expression is
`-1(4)/(35)`
