Solve Multi-Step Measurement Word Problems
To solve multi-step measurement word problems with different units, first convert all measurements to a common unit by multiplying by the appropriate conversion factor, then perform the required operations. This Grade 5 math skill from Eureka Math Chapter 23 covers multiplication of a fraction by a fraction in real-world measurement contexts.
Key Concepts
To solve multi step word problems involving different units of measure, first convert the measurements to a common, larger unit. Then, perform the necessary operations (such as addition or subtraction) to find the final answer.
Common Questions
How do you solve multi-step measurement word problems?
First convert all measurements to a common unit by multiplying by the conversion factor, then perform the required addition, subtraction, or other operations to find the final answer.
What is an example of a multi-step measurement problem?
If a recipe needs 10 ounces of flour and 8 ounces for frosting, find the total in pounds: add 10 plus 8 equals 18 ounces, then convert by multiplying 18 times 1/16 to get 1 and 1/8 pounds.
How do you convert inches to feet using fractions?
Multiply the number of inches by 1/12, since there are 12 inches in a foot. For example, 28 inches times 1/12 equals 28/12 equals 2 and 1/3 feet.
Why must all measurements be in the same unit before adding or subtracting?
Adding measurements in different units (like feet and inches) directly would be like adding apples and oranges; you must convert to a common unit so all the numbers represent the same-sized pieces.
