Question

Assume that you buy 4 kilograms of dragon fruit at a market in Bangkok, Thailand, for 69 bahts. What is the cost of dragon fruit in dollars per pound?

On your paper show the unit fractions used to solve this problem.
1 kilogram = 2.2 pounds
1 US dollar = 31 bahts
The cost is $ per pound

Answer 1

4x2.2= 8.8 pound
69/31= 2.2 $
so 8.8 pounds of dragon fruit costs 2.2$
2.2/8.8= 0.25$
so the cost of dragon fruit in dollars per pound is 0.25$
