Question

Michael purchased 5 1/5 kilograms of sugar and then decided to purchase another 3 1/2 ​ kilograms of the sugar. How many pounds did Michael purchase altogether? Assume 1 kilogram = 2.2 pounds.

Answer 1

To solve:
Add the amounts of sugar together:

`(21)/(5) +(7)/(2)=(42)/(10)+(35)/(10)=(77)/(10)= 7.7`

Then multiply by 2.2 to convert to kg:
7.7•2.2=
16.94

Answer: 16.94 pounds
