Answer:
a) 3/5, 60%
b) 1/15, 0.07
c) 9:1, The ratio means that Jack had spent 9 times more money on shoes than on music, 9/1
Step-by-step explanation:
a) The ratio would be 45:75, simplifying that would be 3/5. Now, 3 divided by 5 is .6, which would be 60%.
b) This ratio would be 5:75, simplifying that would be 1/15. 1 divided by 15 is 0.0666666. Rounding it to the nearest hundreth would get you 0.07
c) The ratio of shoes money and music money would be 9:1. You can find this by making the denominators of each of the fractions the same, so 3/5 multiplied by 3 gets you 9/15. Now, you can easily compare them.
