One way to find a common denominator is by

Lena [83]

Answer:

Step-by-step explanation:

a). $1\frac{3}{5}=1+\frac{3}{5}$

$=1+\frac{3}{5}\times \frac{4}{4}$

$=1+\frac{12}{20}$

$=1\frac{12}{20}$

$1\frac{3}{4}=1+\frac{3}{4}$

$=1+\frac{3}{4}\times \frac{5}{5}$

$=1+\frac{15}{20}$

$=1\frac{15}{20}$

Therefore, common denominator of 20.

b). $2\frac{1}{2}=2+\frac{1}{2}$

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

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

$=2\frac{5}{10}$

$\frac{4}{5}=\frac{4}{5}\times \frac{2}{2}$

$=\frac{8}{10}$

Common denominator of 10.

c). $\frac{3}{8}=\frac{3}{8}\times \frac{6}{6}$

= $\frac{18}{48}$

$\frac{1}{6}=\frac{1}{6}\times \frac{8}{8}$

= $\frac{8}{48}$

Common denominator of 48.
