d. 2/3

  1.  B. 1:3

2.  A.

Step-by-step explanation:

1. Given : Rachel has 6 pairs of black shoes and 2 pairs of red shoes.

Then, the ratio of pairs of red shoes to pairs of black shoes will be :_

Which is written as 1:3.

Hence, the ratio of pairs of red shoes to pairs of black shoes = 1:3

Thus , correct option :  B. 1:3

2. Given : In a probability experiment, Eric flipped a coin 42 times. The coin landed on heads 28 times.

Then, the ratio of heads to tails in this experiment will be :-

Hence, the correct option is : A.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
