## McGraw-Hill Math Grade 4 Answer Key Chapter 9 Lesson 2 Adding Fractions with Denominators 10 and 100

**Add**

Question 1.

\(\frac{3}{10}\) + \(\frac{3}{10}\) = _____________

Answer:

The denominator of both the fractions are same. So we have to add the numerators.

\(\frac{3}{10}\) + \(\frac{3}{10}\) = \(\frac{6}{10}\)

Question 2.

\(\frac{50}{100}\) + \(\frac{20}{100}\) = ______________

Answer:

The denominator of both the fractions are same. So we have to add the numerators.

\(\frac{50}{100}\) + \(\frac{20}{100}\) = \(\frac{70}{100}\)

Question 3.

\(\frac{6}{10}\) + \(\frac{2}{10}\) = _______________

Answer:

The denominator of both the fractions are same. So we have to add the numerators.

\(\frac{6}{10}\) + \(\frac{2}{10}\) = \(\frac{8}{10}\)

Question 4.

\(\frac{4}{10}\) + \(\frac{1}{10}\) = _______________

Answer:

The denominator of both the fractions are same. So we have to add the numerators.

\(\frac{4}{10}\) + \(\frac{1}{10}\) = \(\frac{5}{10}\)

Question 5.

\(\frac{21}{100}\) + \(\frac{47}{100}\) = _______________

Answer:

The denominator of both the fractions are same. So we have to add the numerators.

\(\frac{21}{100}\) + \(\frac{47}{100}\) = \(\frac{68}{100}\)

Question 6.

\(\frac{7}{10}\) + \(\frac{3}{10}\) = _______________

Answer:

The denominator of both the fractions are same. So we have to add the numerators.

\(\frac{7}{10}\) + \(\frac{3}{10}\) = \(\frac{10}{10}\) = 1

Question 7.

Draw three squares of equal size. Show \(\frac{8}{10}\) on one square, \(\frac{80}{100}\) on another, and \(\frac{4}{5}\) on the third. Explain what you see.

Answer:

\(\frac{8}{10}\) = \(\frac{4}{5}\)

\(\frac{80}{100}\) = \(\frac{4}{5}\)
