Question

add.
\\(\frac{4}{10} + \frac{1}{2} = \square\\)
use the model to help you.
\\(\frac{1}{10}\\) \\(\frac{1}{10}\\) \\(\frac{1}{10}\\) \\(\frac{1}{10}\\)
+ \\(\frac{1}{2}\\)

Explanation:

Step1: Find a common denominator

The denominators are 10 and 2. The least common denominator is 10. Rewrite \(\frac{1}{2}\) with denominator 10: \(\frac{1}{2}=\frac{1\times5}{2\times5}=\frac{5}{10}\)

Step2: Add the fractions

Now add \(\frac{4}{10}+\frac{5}{10}\). Since the denominators are the same, add the numerators: \(4 + 5 = 9\), so the result is \(\frac{9}{10}\)

Answer:

\(\frac{9}{10}\)
