Question
What should be added to $6\frac{7}{15}$ to get $8\frac{1}{5}$?

Answer

Let x be added to $6\frac{7}{15}$ to get $8\frac{1}{5}$ Therefore, $6\frac{7}{15}+\text{x}=8\frac{1}{5}$ Thus, we have: $\text{x}=8\frac{1}{5}-6\frac{7}{15}$ $=\frac{41}{5}-\frac{97}{15}$ L.C.M. of 5 and 15 = (5 × 3) = 15$=\frac{(123-97)}{15}$
$\Big(\frac{15}{5}=3,3\times41=123\Big)$
and $\Big(\frac{15}{15}=1,1\times97=97\Big)$
$=\frac{26}{15}$
$=1\frac{11}{15}$
