Question

How much did he spend?

Answer 1

6 dollars

Explanation:

first work out how much of a pound he wanted to buy

3/5 of a pound

divide one pound by five then time that by three

1÷5=0.2

0.2×3=0.6

so 0.6 pounds

now if one pound is 10 dollars

what will 0.6 pounds be?

find how much pounds you get for one dollar

1÷10=0.1

so one dollar buys 0.1 pounds

so times by 6 to get 0.6 pounds for 6 dollars

Answer 2

$6

Explanation:

Glass beads cost $10 per pound

He didn't buy upto one pound, just 3/5

`cost \: = (3)/(5) * 10 \\ = 6`

He spent $6
