Question

One way to find a common denominator is by

Answer 1

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.
