Spectrum Math Grade 5 Chapter 5 Lesson 5.1 Adding & Subtracting with Like Denominators Answers Key

Denominators are called common when they share the same number.

To add fractions with like denominators, add the numerators and use the common denominator.
\(\frac{1}{5}\) + \(\frac{2}{5}\) = \(\frac{1+2}{5}\) = \(\frac{3}{5}\)
To subtract fractions with like denominators, subtract the numerators and use the common denominator.
\(\frac{7}{10}\) – \(\frac{3}{10}\) = \(\frac{7-3}{10}\) = \(\frac{4}{10}\) = \(\frac{2}{5}\)
