Question

Add $\frac{2}{7}and\frac{3}{14}$ and express the sum in its lowest terms.

Answer 1

$L.C.Mof7and14=7\times 2=14$
Now,
$\frac{2}{7}=\frac{2\times 2}{7\times 2}=\frac{4}{14}$
$\therefore \frac{2}{7}+\frac{3}{14}=\frac{4}{14}+\frac{3}{14}=\frac{4+3}{14}=\frac{7}{14}$
Reducing to the lowest form, we get
$\frac{7}{14}=\frac{7÷7}{14÷7}=\frac{1}{2}$
