Answer:   1.  B. 1:3

2.  A. [tex]\dfrac{2}{3}[/tex]

Step-by-step explanation:

  • The ratio of m to n is written as [tex]\dfrac{m}{n}[/tex]

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 :_

[tex]\dfrac{\text{No. of pairs of red shoes}}{\text{No. of pairs of black shoes}}\\\\=\dffrac{2}{6}=\dfrac{1}{3}[/tex]

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 :-

[tex]\dfrac{28}{42}=\dfrac{2}{3}[/tex]

Hence, the correct option is : A. [tex]\dfrac{2}{3}[/tex]
