Question

Subtract fractions
3-2/7

Answer 1

To subtract \( \frac{2}{7} \) from \( 3 \), you can express \( 3 \) as a fraction with the same denominator.

1. Write \( 3 \) as \( \frac{21}{7} \) since \( 3 = \frac{3 \times 7}{1 \times 7} = \frac{21}{7} \).

2. Now, subtract \( \frac{2}{7} \) from \( \frac{21}{7} \):

\[
\frac{21}{7} - \frac{2}{7} = \frac{21 - 2}{7} = \frac{19}{7}
\]

So, \( 3 - \frac{2}{7} = \frac{19}{7} \).

You can also convert \( \frac{19}{7} \) into a mixed number:

\[
\frac{19}{7} = 2 \frac{5}{7}
\]

Thus, the final result is \( \frac{19}{7} \) or \( 2 \frac{5}{7} \).
