What is 1over7 plus 3over 21?

Answer 1

To add ( \frac{1}{7} ) and ( \frac{3}{21} ), first convert ( \frac{3}{21} ) to a fraction with a denominator of 7. Since ( \frac{3}{21} = \frac{1}{7} ), the addition becomes ( \frac{1}{7} + \frac{1}{7} = \frac{2}{7} ). Thus, ( \frac{1}{7} + \frac{3}{21} = \frac{2}{7} ).
