Answers

Answer 1

Answer:

1. C) 4 ft

2. B) 3 yds

3. C) 15840 ft

4. D) 128 oz

5. A) 105 oz

Step-by-step explanation:

For No. 1, to find how many feet, you can divide the number of inches by how many inches in a foot, or 12:

48/12 = 4 ft

For No. 2, to find how many yards, you would do the same. This time, there's 3 ft in a yard. You can also develop strategies for solving these. A ratio is a good way to visually see the problem:

3 ft 9 ft

----- = -----

1 yd ? yd

Cross multiply:

3 · ? = 9

? = 3

For No. 3, to find how many feet in 3 miles, first recall how many feet in 1 mile. That's 5280 ft.

We want 3 of those, so you would multiply it:

5280 · 3 = 5280 + 5280 + 5280

= 10560 + 5280

= 15840

For No. 4, you can use a ratio again:

16 oz ? oz

-------- = --------

1 lb 8 lb

Cross multiply:

16 (8) = ?

128 = ?

For No. 5, you can use the same ratio as No. 4:

16 oz ? oz

-------- = --------

1 lb 6.5 lb

Cross multiply:

16 (6 1/2) = ?

(16 · 6) + (16 · 1/2) = ?

96 + 8 = ?

104 = ?
