Solve Word Problems Involving a Fraction of a Measurement

Solve Word Problems Involving a Fraction of a Measurement is a Grade 5 math skill in Eureka Math, Chapter 21: Multiplication of a Whole Number by a Fraction, where students translate real-world measurement contexts into multiplication expressions and solve problems such as finding 3/4 of 24 inches. Students practice interpreting fractional parts of length, capacity, and weight in applied contexts.

Key Concepts

To find a fractional part of a measurement in a word problem, translate the problem into a multiplication expression. This involves multiplying the fraction by the total measurement, after converting the measurement into a smaller, more manageable unit.

Common Questions

How do you find a fraction of a measurement?

Multiply the measurement by the fraction. For example, to find 3/4 of 24 inches, compute 3/4 × 24 = 18 inches. You can also divide by the denominator first, then multiply by the numerator.

What types of measurements are used in fraction word problems?

Grade 5 word problems use length (inches, feet, meters), capacity (liters, gallons), and weight (ounces, pounds, grams) to create real-world fraction-of-a-measurement contexts.

What is Eureka Math Grade 5 Chapter 21 about?

Chapter 21 covers Multiplication of a Whole Number by a Fraction, including solving measurement word problems that require finding a fractional part of a given quantity.

What is a good strategy for fraction of a measurement problems?

Draw a tape diagram to represent the whole measurement, divide it into equal parts matching the denominator, then shade the number of parts matching the numerator to find the answer visually.
