Simplify:61 6 -51 5 +31 3 - Vidyadip

Question

Simplify:$6\frac{1}{6}-5\frac{1}{5}+3\frac{1}{3}$

✓

Answer

We have:$6\frac{1}{6}-5\frac{1}{5}+3\frac{1}{3}$
$=\frac{37}{6}-\frac{26}{5}+\frac{10}{3}$
$\begin{array}{c|c}2&6,5,3\\\hline3&3,5,3\\\hline5&1,5,1\\\hline&1,1,1\end{array}$
L.C.M. of 6, 5 and 3 = (2 × 5 × 3) = 30 $=\frac{(185-156+100)}{30}$ $\Big(\frac{30}{6}=5,5\times37=185\Big)$ $\Big(\frac{30}{5}=6,6\times26=156\Big)$ and $\Big(\frac{30}{3}=10,10\times10=100\Big)$$=\frac{(285-156)}{30}$
$=\frac{129}{30}$
$=\frac{43}{10}$
$=4\frac{3}{10}$
