Question

What should be added to $5\frac{1}{5}$ to get $7\frac{3}{7}$?

Answer 1

Let the number = x

According to problem

$x+5\frac{1}{5}=7\frac{3}{7}$

$x+\frac{26}{5}=\frac{52}{7}$

$x=\frac{52}{7}-\frac{26}{5}$

$x=\frac{260-182}{35}$

$x=\frac{78}{35}$

$\therefore$ The number is $\frac{78}{35}$
