1)
1 yard = 3 feet
x yard = 18 feet
By crossmultiplying,
3 * x = 1 * 18
3x = 18
x = 18/3 = 6
Answer is 6 yds
2) 1 pound = 16 ounces
x pounds = 72 ounces
By crossmultiplying,
16 * x = 1 * 72
16x = 72
x = 72/16 = 4.5
Answer is 4.5 lb
3)
1 pound = 16 ounces
2 pounds = x ounces
By crossmultiplying,
1 * x = 2 * 16
x = 32
Answer is 32 oz
4)
1 mile = 5280 feet
1.25 miles = x feet
By crossmultiplying,
1 * x = 1.25 * 5280
x = 6600
Answer is 6600 ft
5)
1 US pint = 0.5 US quarts
x pints = 2.75 quarts
By crossmultiplying,
1 * 2.75 = 0.5 * x
0.5x = 2.75
x = 2.75/0.5 = 5.5
Answer is 5.5 pt
