Question

What should be added -7/8
to get 4/9
​

Answer 1

Take LCM = 72
-7/8 = -63/72
4/9 = 32/72

-63/72 + x = 32/72
x = 32/72 + 63/72
x = 95/72 is the answer

Hope it helps you

Answer 2

let be second no. is x

Answer:

-7/8+x=4/9

x=4/9+(-7/8)

x=4/9-7/8

our lcm is taking.. 72..

so

x=32-63/72

x=-21/72

let check our answer by subsituiting x=-21/72

so our equation is..

-7/8+(-21/72)=4/9

so

-7/8-21/72=4/9

by solving you get

4/9=4/9

hence l.h.s=r.h.s
