Question

what should be added to 3 7/15 to get 8 1/5 ?

Answer 1

Here u go..

When 8 1/5 is subtracted from 3 7/15
=8 1/5-3 7/15
=41/5-52/15
=73-52/15

=21/15
=1 6/15

Hence 1 6/15 should be added to 3 7/15 to get 8 1/5..

Answer 2

First number= 3 hole 7/15=52/15

Let second number= x

x+52/15= 8 hole1/5

x+52/15=41/5

x=41/5-52/15

x=71/15

Then second number= x=71/15
