A comprehensive course preparing 5th graders for the MAP math assessment, covering essential concepts and real-world math skills.
Multiplying and dividing fractions lets us figure out things like how much of an ingredient we need or how to split something fairly.
To multiply fractions, multiply the numerators and the denominators:
\[ \frac{2}{3} \times \frac{4}{5} = \frac{8}{15} \]
To divide fractions, multiply the first fraction by the reciprocal of the second:
\[ \frac{3}{4} \div \frac{2}{5} = \frac{3}{4} \times \frac{5}{2} = \frac{15}{8} \]
This helps us in recipes, crafts, and any time we need to work with parts of parts!
\[\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}\]
Finding out how much of a recipe you need if you're making half a batch.
Splitting \( \frac{3}{4} \) of a pizza between 2 people.
Multiplying and dividing fractions help us solve more complex real-world problems involving parts of things.
