Question

Gina checked 20 markers. 7 of them were

working. What percent of her markers were
not working?

Answer 1

65%

Explanation:

20-7=13, 13/20=0.65, 0.65*100=65 (Which leaves you with your answer)

Answer 2

Explanation:

1. find how many are not working

20 - 7 = 13

2. make this into a fraction:

13/20

3. make equivalent to x/100

do this by multiplying by 5

13/20 = 65/100

65/100 is 65% which don't work
