Question

A girl spends 1/5 of her pocket money on sweets and 2/3 on records. What fraction has she left?

Answer 1

Let money with girl = 1

Money spend on sweets=1/5

money spend on records=2/3

Total money spend=1/5+2/3.

Money left with her = 1-1/5+2/3

On taking LCM i.e 15

$\frac{15 - 3 + 10}{15} \\ = > \frac{15 - 13}{15} \\ = > \frac{2}{15}$

Hence , money left with her is 2/15.

Answer 2

Answer:

$\frac{1}{ 5} + \frac{2}{3} + x = 1$

$\frac{1}{5} \times \frac{3}{3} + \frac{2}{3} \times \frac{5}{5} + x = 1$

$\frac{3}{15} + \frac{10}{15} + x = 1$

$\frac{3 + 10}{15} + x = 1$

$\frac{13}{15} + x = 1$

$x = 1 - \frac{13}{15}$

$x = \frac{15}{15} - \frac{13}{15}$

$x = \frac{15 - 13}{15}$

$x = \frac{2}{15}$

•°• Therefore she has 2/15 fraction left.
