Question

$4\frac{1}{5}+1\frac{1}{5}$

Answer

When we add mixed numbers, we add whole numbers to whole numbers and fractions to fractions.

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

Remember, when we are adding fractions we must have common denominators and we only add the numerators.

Compare your answer with the correct one above

Question

$2\frac{5}{10}+5\frac{3}{10}$

Answer

When we add mixed numbers, we add whole numbers to whole numbers and fractions to fractions.

$\frac{5}{10}+\frac{3}{10}=\frac{8}{10}$

Remember, when we are adding fractions we must have common denominators and we only add the numerators.

$\frac{8}{10}$ can be reduced by dividing to both sides.

$\frac{8}{10}\div\frac{2}{2}=\frac{4}{5}$
