MAP 5th Grade Math

A comprehensive course preparing 5th graders for the MAP math assessment, covering essential concepts and real-world math skills.

Advanced Topics

Multiplying and Dividing Fractions

Multiplying Fractions

To multiply fractions, multiply the numerators together and the denominators together.

\( \frac{2}{3} \times \frac{4}{5} = \frac{8}{15} \)

Dividing Fractions

Dividing fractions means multiplying by the reciprocal (flip the second fraction).

\( \frac{3}{4} \div \frac{2}{5} = \frac{3}{4} \times \frac{5}{2} = \frac{15}{8} \)

Real-Life Uses

These skills help when you're doubling a recipe (multiplying) or sharing food equally (dividing).

Key Formula

\[\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}\]

Examples

  • Cutting a cake recipe in half: \( \frac{3}{4} \times \frac{1}{2} = \frac{3}{8} \) cups.

  • Splitting \( \frac{5}{6} \) of a pizza between 2 people: \( \frac{5}{6} \div 2 = \frac{5}{12} \).

In a Nutshell
