McGraw-Hill My Math Grade 4 Answer Key Chapter 11 Lesson 6 Convert Customary Units of Weight
Recall that to convert from a larger unit to a smaller unit, multiply.
Math in My World
Example 1
Leigh needs to buy 4 pounds of vegetable burger patties. The table shows the number of ounces in each package of patties. How many packages will Leigh need to buy?
Convert 4 pounds to ounces.
Because pounds are larger than ounces, multiply.
There are 16 ounces in a pound, so multiply 4 by 16.
4 × 16 = ______________
4 pounds = _____________ ounces
So, Leigh will need to buy ________________ package(s).
Answer:
4 × 16 = 64
4 pounds = 64 ounces
So, Leigh will need to buy 2 package(s).
Example 2
Use the table to find how many pounds a Stegosaurus weighed.
To find the weight of a Stegosaurus in pounds, multiply th6 number of tons by 2,000.
3 × 2,000 = ______________
So, a Stegosaurus weighed ______________ pounds.
Answer:
3 × 2,000 = 6000
So, a Stegosaurus weighed 6000 pounds.

Question 18.
Mathematical PRACTICE Plan Your Solution Tiffany weighed 7 pounds 12 ounces when she was born. Her weight doubled after four months. How much did Tiffany weigh after four months?
Answer:
Given that: Tiffany weighed 7 pounds 12 ounces when she was born.
Her weight doubled after four months.
2 times 7 equals 14 pounds and 12 times 2 equal 24 ounces .
1 pounds equals to 16 oz.
24 oz can also be written as 16oz + 8oz or 1 pound 8 oz.
Therefore, her weight after 4 months will be 15 pounds 8 ounces.
Question 19.
Building on the Essential Question How can I convert measurements of weight?
Answer:
To convert smaller units of weight to larger units of weight,divide by the number of small units that are in one of the large units. To convert larger units of weight to smaller units of weight, multiply by the number of small units that are in one of the large units.

Question 10.
Brent’s pick-up truck can carry \(\frac{1}{5}\) ton. Nina’s pick-up truck can carry 500 pounds. Whose pick-up truck can carry more weight? Explain.
Answer:
Given that: Brent’s pick-up truck can carry \(\frac{1}{5}\) ton. Nina’s pick-up truck can carry 500 pounds.
In order to compare the weight, we need to first convert them into equal measurements.
Let us convert the ton into pounds.
1 tons equals 2000 lb.
\(\frac{1}{5}\) ton equals to 400 lb.
Brent’s pick-up truck can carry 400 lb. Nina’s pick-up truck can carry 500 pounds.
From above observation, we can say that Nina’s pick up truck can carry more weight.
