Question

Every week malik spends 5 2/15 hours doing his math homework and 2 13/30 hours doing his science homework. Estimate how much more time malik spends on his math homework.

Answer 1

This is Simple, Just Subtract Time taken by Science homework from time taken by Maths homework..

$= 5 \frac{2}{15} - 2 \frac{13}{30} \\ = \frac{150}{15} - \frac{73}{30} \\ = \frac{300 - 73}{30} \\ = \frac{227}{30} \\ = 7 \frac{17}{30} \: hours \: more.$
