sam has a collection of toy cars. His favorites are the 27 red ones which make up 60% of his collection. How many toy cars does

sladkih [1.3K]

Well, if 27 cars make up 60% of his entire collection, so you'd want to change 60% into a decimal, which would make it .6. Then, you'd want to divide .6 by 27. You should hopefully get 45 as your answer.
Hopefully that helped! :)

If a fraction is equal to 2/9

Illusion [34]

Answer:

18/81

Step-by-step explanation:

the current fraction adds up to 11 so to get 99 you would need to multiply both the numerator and the denominator by 9 to get a sum of 99

so 2 x 9 = 18 and 9 x 9 =81

so answer is 18/81
