Problem 1:
> One pound equals 0.45 kilograms. Cathy weighs 81 kilograms on the bathroom scale. Determine her weight in pounds.
Step 1: We know:
- 1 pound = 0.45 kg
So, to convert kilograms to pounds, we divide by 0.45.
Calculation:
$$
\text{Weight in pounds} = \frac{81}{0.45}
$$
$$
= \frac{81}{0.45} = 180
$$
✔ Answer: 180.00 pounds

Problem 2:
> Mr. Williams buys 12 gallons of ivory paint to do up the exteriors of his home. How much does one gallon of paint cost if he is billed a total of $305.40 for this purchase?
Step 1: Total cost ÷ number of gallons = cost per gallon
$$
\frac{305.40}{12} = ?
$$
$$
305.40 ÷ 12 = 25.45
$$
✔ Answer: $25.45 per gallon

Problem 3:
> At a farmer’s market, Kenny picks 5 cantaloupes that weigh a total of 27.52 pounds. Find the average weight of one cantaloupe.
Step 1: Total weight ÷ number of cantaloupes
$$
\frac{27.52}{5} = 5.504
$$
Round to
two decimal places: 5.50
✔ Answer: 5.50 pounds

Problem 4:
> Martin, a carpenter, wants to make a spice rack for the kitchen. He cuts a 16.24 feet long plank into 5 pieces of equal length. What is the length of each piece of wood?
Step 1: Divide total length by number of pieces
$$
\frac{16.24}{5} = 3.248
$$
Round to
two decimal places: 3.25
✔ Answer: 3.25 feet

Problem 5:
> Nina goes to the neighborhood store to buy 14 rolls of paper towels. If she pays $20.02 in all for her purchase, how much does one roll of paper towel cost?

$$
✔ Answer: $1.43 per roll
