the first one is A, because you divide both numbers by two, and make sure they are in the right order.
the answer to the second one is 2/3, because 28 divided by 42 is .66666
Answer: 1. B. 1:3
2. A. [tex]\dfrac{2}{3}[/tex]
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 :_
[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]
