Fast and hurry because i really don’t don’t

So the question is asking which pair of fractions in the box would have the same common denominator. Basically, look at the denominator of each fraction pair and see if both numbers can go into each common denominator you were given. I'll explain further.

Common denominator: 24) The pairs that correspond to this denominator is 3/4 , 2/6 because the denominators of both fractions (4 and 6) go into 24 evenly.

Common denominator: 15) The answer is 1/3 , 3/5 because 3 and 5 go into 15 evenly.

Common denominator: 9) The answer is 2/3 , 4/9 becuase 3 and 9 go into 9 evenly.

answer: x

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
