What should be added to $-\frac{15}{7}$ to get $\frac{4}{35}$
Given: $-\frac{15}{7}$
To find: What should be added to $-\frac{15}{7}$ to get $\frac{4}{35}$
Solution:
Let the number be $x$
$-\frac{15}{7} + x$ = $\frac{4}{35}$
$x $ = $\frac{4}{35}$ + $\frac{15}{7} $
L C M of 35 , 7 is 35
$x $=$\frac{4}{35}$ + $\frac{15\times5}{7\times5} $
$x $=$\frac{4}{35}$ + $\frac{75}{35} $
$x $=$\frac{4+75}{35}$
$x $=$\frac{79}{35}$
Therefore we will add $\frac{79}{35}$ to $-\frac{15}{7}$ to get $\frac{4}{35}$
