Add, answer as a mixed number in simplest form.

1, 1/2 + 1, 1/5 = [__], [__]/[__]
Enter the whole number.

1 answer

To solve \(1 \frac{1}{2} + 1 \frac{1}{5}\), we first convert the mixed numbers to improper fractions.

  1. Convert \(1 \frac{1}{2}\): \[ 1 \frac{1}{2} = 1 + \frac{1}{2} = \frac{2}{2} + \frac{1}{2} = \frac{3}{2} \]

  2. Convert \(1 \frac{1}{5}\): \[ 1 \frac{1}{5} = 1 + \frac{1}{5} = \frac{5}{5} + \frac{1}{5} = \frac{6}{5} \]

Now we can add the two improper fractions: \[ \frac{3}{2} + \frac{6}{5} \]

To add these fractions, we need a common denominator. The least common multiple (LCM) of 2 and 5 is 10.

Convert each fraction to have the denominator of 10: \[ \frac{3}{2} = \frac{3 \times 5}{2 \times 5} = \frac{15}{10} \] \[ \frac{6}{5} = \frac{6 \times 2}{5 \times 2} = \frac{12}{10} \]

Now we can add the two fractions: \[ \frac{15}{10} + \frac{12}{10} = \frac{27}{10} \]

Next, we convert the improper fraction \(\frac{27}{10}\) back to a mixed number: \[ 27 \div 10 = 2 \quad \text{(whole number)} \] \[ \text{Remainder: } 27 - 20 = 7 \] So, \(\frac{27}{10} = 2 \frac{7}{10}\).

Thus, the answer in mixed number form is \(2 \frac{7}{10}\).

The whole number is: \[ \boxed{2} \]
