Question

Rohan purchased 4 ½ kg potatoes and 7  4/5 kg onions. Find the total weight of vegetables purchased by him?​

Answer 1

Answer:

Weight of potatoes =

$4\frac{1}{2}= \frac{9}{2}kg$

Weight of onions =

$7\frac{4}{5}= \frac{39}{5}kg$

$4\frac{1}{2} + 7\frac{4}{5} \\ \\ = \frac{9}{2} + \frac{39}{5} \\ \\ = lcm = 2 \times 5 \times = 10 \\ \\ = \frac{45}{10} + \frac{78}{10} \\ \\ = \frac{123}{10} = 12.3kg \: of \: vegetables \:$
