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.

Step-by-step explanation:

the 2 angles marked with orange and green are equal becos the question said that the indicated angles are congruent meaning same deg. so 180 - that given angle = the 2 marked angles (based on the rule known as angles on a str line are supplementary)

since the 2 marked angles are same, you can say that d and k are parallel due to the rule of alternate angles
