Question

Add the fractions
7/20 + 3/5

Answer 1

To add the fractions \( \frac{7}{20} \) and \( \frac{3}{5} \), we need a common denominator.

The denominator of the first fraction is 20, and the denominator of the second fraction is 5. The least common multiple (LCM) of 20 and 5 is 20.

Now, we can convert \( \frac{3}{5} \) to have a denominator of 20:

\[
\frac{3}{5} = \frac{3 \times 4}{5 \times 4} = \frac{12}{20}
\]

Now, we can add the fractions:

\[
\frac{7}{20} + \frac{12}{20} = \frac{7 + 12}{20} = \frac{19}{20}
\]

So, \( \frac{7}{20} + \frac{3}{5} = \frac{19}{20} \).
