Solve 4⅕ - 2⅘

1 answer

To solve \( 4\frac{1}{5} - 2\frac{2}{5} \), we can first convert the mixed numbers into improper fractions.

  1. Convert \( 4\frac{1}{5} \): \[ 4\frac{1}{5} = 4 \times 5 + 1 = 20 + 1 = 21 \] So, \( 4\frac{1}{5} = \frac{21}{5} \).

  2. Convert \( 2\frac{2}{5} \): \[ 2\frac{2}{5} = 2 \times 5 + 2 = 10 + 2 = 12 \] So, \( 2\frac{2}{5} = \frac{12}{5} \).

Now we can subtract the two improper fractions: \[ \frac{21}{5} - \frac{12}{5} = \frac{21 - 12}{5} = \frac{9}{5} \]

Next, we can convert \( \frac{9}{5} \) back to a mixed number: \[ \frac{9}{5} = 1\frac{4}{5} \]

Therefore, the solution to \( 4\frac{1}{5} - 2\frac{2}{5} \) is: \[ \boxed{1\frac{4}{5}} \]
