Question

Jamie has $60$ countries. He gives $\frac{1}{3}$ of his countries to Sam and $\frac{1}{4}$ to Sally. How many countries does Jamie is left with?

Answer 1

He gave $\frac{1}{3}$ and $\frac{1}{4}$ to others

$\therefore$ $\frac{1}{3}+\frac{1}{4}=\frac{7}{12}$

$(1-\frac{7}{12})$th part he have

$\frac{5}{12}\times 60=25$

countries left $=25$
