2. 22.525 gallons

3. 437.4 yds

Explanation:

1. 345/2.2 (since 2.2 lbs equals 1 kg you would divide that by the number of pounds to find kg).

2. 85 x 1.06 = 90.1 (to find the number of qts)

90.1/4 = 22.525 (there are 4 quarts in a gallon so you would divide by 4)

3. 400 x 39.37 = 15,748 (multiply number of meters by the number of inches)

15,748/36 = 437.4 (divide by 36 since you are moving to a bigger unit)
