b. Describe the rule for converting yards to inches.
c. How many inches are in 15 yards?
d. Jacob says that he can find the number of inches in 15 yards by tripling the number of inches in 5 yards. Does his strategy work? Why or why not?
e. A blue rope in Garret’s camping backpack is 6 yards long. The blue rope is 3 times as long as a red rope. A yellow rope is 2 feet 7 inches shorter than the red rope. What is the difference in length between the blue rope and the yellow rope?
Answer:
B.To convert yards into inches
Multiply the number of yards x 36
c. 1 yard = 36 inches
15 yards = 15 x 36 = 540
Therefore, 15 yards = 540 inches.
d. Yes, Jacob strategy is right.
15 yards can be shown as 5 yards x 3
1 yard = 36 inches
15 yards = 540 inches
5 yards tripling by 3 =
5 yards = 5 x 36 = 180
5 yards = 180 inches
180 inches x 3 = 540
e. Given, the length of blue rope = 6 yards long
6 yards = 18 feet
Also given, the blue rope is 3 times as long as a red rope
so, length of red rope = 2 yards = 6 feet
A yellow rope is 2 feet 7 inches shorter than red rope
So, 6 feet – 2 feet 7 inches
= 3 feet 5 inches
Now,
18 feet – 3 feet 5 inches = 14 feet 7 inches.
Therefore, the length difference between the blue rope and the yellow rope is 14 feet 7 inches.
