Question

What number should be added to -7/77 to get 1/22

Answer 1

Given ,

Let the number to be added be x ,

then ,

-( 7 / 77 ) + x = 1 / 22

x = ( 1 / 22 ) + ( 7 / 77 )

x = ( 1 / 22 ) + ( 1 /11 )

x = ( 1 / 22 ) + (1*2 / 11*2)

x =  1 / 22   +   2 / 22

x = ( 1 + 2 ) / 22

x = 3 / 22

Hence 3/22 should be added.
