Question

student handout: unit 3 lesson 3

1. 4.5 yards is ______________ feet

4.5 x 3 feet per yard = 13.5 feet
so... 4.5 yds is 13.5 ft.
practice

1. convert each measurement to the unit specified.

9 lb = ____________ oz.\t136 yd = ____________ ft
36960 ft = ____________ mi.\t156 in =____________ ft
2.5 mi = ____________ yd\t5000 lb = ____________ ton

Explanation:

Step1: Recall conversion factor for pounds to ounces

There are 16 ounces in 1 pound. So for 9 lb, we multiply by 16.
$9\times16 = 144$

Step2: Recall conversion factor for yards to feet

There are 3 feet in 1 yard. For 136 yd, we multiply by 3.
$136\times3=408$

Step3: Recall conversion factor for feet to miles

There are 5280 feet in 1 mile. For 36960 ft, we divide by 5280.
$36960\div5280 = 7$

Step4: Recall conversion factor for inches to feet

There are 12 inches in 1 foot. For 156 in, we divide by 12.
$156\div12 = 13$

Step5: Recall conversion factor for miles to yards

There are 1760 yards in 1 mile. For 2.5 mi, we multiply by 1760.
$2.5\times1760=4400$

Step6: Recall conversion factor for pounds to tons

There are 2000 pounds in 1 ton. For 5000 lb, we divide by 2000.
$5000\div2000 = 2.5$

Answer:

9 lb = 144 oz.
136 yd = 408 ft
36960 ft = 7 mi.
156 in = 13 ft
2.5 mi = 4400 yd
5000 lb = 2.5 ton
