Question

What should be subtracted from the sum of 7/8&4/15 to get 9/40

Answer 1

SOLUTION:-

GIVEN》 7/8&4/15

= 7/8+4/15

=( 105+31)/120

= 136/120 =17/15
____________________________

= 17/15 - 9/40

= (136-27)/120

= 109/120

subtracted from the sum of 7/8&4/15 = 109/120

then get 9/40 |

Answer 2

Let x should be subtracted,

According to the question,


=> (7/8 + 4/15) + x =9/40

=> {(105+32)/60 -9/40 = x

=> (137)/60 -9/40 = x

=> (274-27)/120 =x

=> (247)/(120) = x



247/120 should be subtracted


I hope this will help you
