2/10 + 1/3

1 answer

To add the fractions \( \frac{2}{10} \) and \( \frac{1}{3} \), we first need to find a common denominator. The least common multiple (LCM) of 10 and 3 is 30.

Now, we will convert each fraction to have a denominator of 30:

  1. Convert \( \frac{2}{10} \): \[ \frac{2}{10} = \frac{2 \times 3}{10 \times 3} = \frac{6}{30} \]

  2. Convert \( \frac{1}{3} \): \[ \frac{1}{3} = \frac{1 \times 10}{3 \times 10} = \frac{10}{30} \]

Now we can add the two fractions: \[ \frac{6}{30} + \frac{10}{30} = \frac{6 + 10}{30} = \frac{16}{30} \]

Next, we can simplify \( \frac{16}{30} \): \[ \frac{16}{30} = \frac{8}{15} \quad \text{(dividing both the numerator and denominator by 2)} \]

Thus, the final result is: \[ \frac{8}{15} \]
