4 Evaluate \( \frac{3}{10}+\frac{17}{100} \)

To evaluate \( \frac{3}{10}+\frac{17}{100} \), it’s best to express both fractions with a common denominator. The least common denominator for 10 and 100 is 100. Now, convert \( \frac{3}{10} \) to have 100 as the denominator: \[ \frac{3}{10} = \frac{3 \times 10}{10 \times 10} = \frac{30}{100} \] Now we can add the two fractions: \[ \frac{30}{100} + \frac{17}{100} = \frac{30 + 17}{100} = \frac{47}{100} \] Thus, the result is \( \frac{47}{100} \) or 0.47 in decimal form.
