Question

Ana was given $180 for her birthday. She spent 1/3 of her money on a helmet. She spent 13/20 of her money on a skateboard. The rest was spent on stickers. How much did Ana spend on stickers?

Answer 1

$3

Step-by-step explanation:

The equation we would be looking at is 180 - 180(
`(1)/(3)`) - 180(
`(13)/(20)`)

180(
`(1)/(3)`) =
`(180)/(3)` = 60

180(
`(13)/(20)`) =
`(2340)/(20)` = 117

Now the equation is 180 - 60 - 117

180 - 60 - 117 = 3
