Answer key and explanations

  1. B. \(\frac{5}{8}\)

    They both ate pieces from the same pizza! Add them with like denominators: \(\frac{3}{8}+\frac{2}{8}=\frac{5}{8}\) of the pizza altogether.

  2. A. \(\frac{4}{10}\)

    The ribbon was cut, so we subtract the cut part from the total. \(\frac{7}{10}-\frac{3}{10}=\frac{4}{10}\) meter of ribbon left.

  3. A. \(\frac{3}{6}\)

    Both friends shared from the same pie, so add the fractions: \(\frac{2}{6}+\frac{1}{6}=\frac{3}{6}\) of the pie they ate together.

  4. B. \(\frac{2}{4}\)

    The recipe needs more flour than Noah has. Find the difference: \(\frac{5}{4}-\frac{3}{4}=\frac{2}{4}\) cups more flour needed.

  5. A. \(\frac{5}{5}\)

    Ava read parts on two different days. Add the fractions: \(\frac{4}{5}+\frac{1}{5}=\frac{5}{5}\), which means she read the whole book!

  6. B. \(\frac{11}{12}\)

    The flower bed has two types of flowers. Add the parts with like denominators: \(\frac{8}{12}+\frac{3}{12}=\frac{11}{12}\) of the flower bed was planted.

  7. B. \(1\frac{1}{4}\)

    Sam used some string, so subtract the amount used from what he started with: \(2\frac{2}{4}-1\frac{1}{4}=1\frac{1}{4}\) meters of string remains.

  8. A. \(\frac{2}{10}\)

    The chocolate bar is shared, but some is left over. Step 1: Add what was eaten: \(\frac{5}{10}+\frac{3}{10}=\frac{8}{10}\). Step 2: Subtract from the whole: \(\frac{10}{10}-\frac{8}{10}=\frac{2}{10}\) left uneaten.
