Question

Sam bought 2 7⁄5 kg of flour in one week and 3 4⁄15 kg of flour in second week.

Find the flour Sam bough altogether ?​

Answer 1

To calculate the quantity of flour he bought altogether, we have to add the both quanties.

$2 \frac{7}{5} + 3 \frac{4}{15} \\ \frac{17}{5} + \frac{49}{15} \\ \frac{51 + 49}{15} \\ \frac{100}{15} = \frac{20}{3} = 6\frac{2}{3} \: answer$
