Question

(-2/7)-(-5/3)=
i have an answer , but i don’t understand how we got to the answer

Answer 1

-2/7 - (-5/3)

First make the denominators equal by using LCM or the way you have learnt

But here we can multiply 7 and 3
Which is 21

So

⁻²⁄₇ 7 x 3 = 21

-2 x 3 = -6
Fraction = -6/21


-5/3 3 x ? = 21
3 x 7 = 21

-5 x 7 = ?
-5 x 7 = -35


Fraction = -35/21

-6/21 - (-35/21)
= 29/21
I think it’s correct mark me as brainliest plsss
