Question

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

Answer 1

let x be added to 37/15 to get 81/25
i.e- 37/15 + x= 81/15
or,. x= 81/15 - 37/15
x=44/15

Answer 2

To Find :

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

Solution:

Number 1 = $3\frac{7}{15}=\frac{52}{15}$

Number 2= $8\frac{1}{5}=\frac{41}{5}$

we are supposed to find what should be added to 3 7/15 to get 8 1/5 ?

Let the number be x

So,$\frac{52}{15}+x=\frac{41}{5}\\x=\frac{41}{5}-\frac{52}{15}\\x=\frac{123-52}{15}\\x=\frac{71}{15}=4\frac{11}{15}$

Hence $4\frac{11}{15}$ should be added to 3 7/15 to get 8 1/5
