Question
What should be added to $7\frac{4}{15}$ to get $8\frac{2}{5}?$
✓
Answer
For finding the required fraction, we have to subtract $7\frac{4}{15}$ from $8\frac{2}{5}$
$\therefore$ Required number $=8\frac{2}{5}-7\frac{4}{15}$
$=\frac{42}{5}-\frac{109}{15}$
$=\frac{126-109}{15} (LCM $ of $5, 15 = 15)$
$=\frac{17}{15}=1\frac{2}{15}$
$\therefore$ Required number $=8\frac{2}{5}-7\frac{4}{15}$
$=\frac{42}{5}-\frac{109}{15}$
$=\frac{126-109}{15} (LCM $ of $5, 15 = 15)$
$=\frac{17}{15}=1\frac{2}{15}$

A circular flower garden has an area of $314 m^2$. A sprinkler at the centre of the garden can cover an area that has a radius of $1 2 ~ m$. Will the sprinkler water the entire garden? (take $\pi=3.14$ )
TIPS Firstly, find the area of circular part that sprinkler can cover by using area $=\pi$ (radius) ${ }^2$. Then, if this area is larger than area of garden, then sprinkler can water the entire garden, otherwise not.
