Question

What number should be added to-5/8so as to get-3/2?

Answer 1

Answer :-

Let the number be x.

$\rightarrow{\sf{\dfrac{-5}{8} + x = \dfrac{-3}{2}}}$

$\rightarrow{\sf{x = \dfrac{-3}{2} + \dfrac{5}{8}}}$

$\rightarrow{\sf{x = \dfrac{-12 + 5}{8}}}$

$\rightarrow{\sf{x = \dfrac{-7}{8}}}$

Verification :-

Take L.H.S. ;

$\rightarrow{\sf{\dfrac{-5}{8} + \dfrac{-7}{8}}}$

$\rightarrow{\sf{\dfrac{-12}{8}}}$

$\rightarrow{\sf{\dfrac{-3}{2} = R.H.S.}}$

Hence, Verified !!

$\boxed{\sf{\dfrac{-7}{8} \ should\ be\ added.}}$

Answer 2

Answer:

x+(-5/8) =-3/2

x-5/8=-3/2

x = -3/2+5/8=(-12+5)/8=-7/8
