Question

There were an equal number of red balls and blue balls in a basket. After 20 red balls and 28 blue balls are removed from the basket, the ratio of the number of red balls
to the number of blue balls becomes
5:3. Find the total number of red balls in the basket.​

Answer 1

Answer:

40

Step-by-step explanation:

Let the total number of balls be x

(x-20)/(x-28) =5/3

3(x-20)=5(x-28)

3x-60=5x-140

2x=80

x=40

Answer 2

Answer:

40

Step-by-step explanation:

Let the total number of balls be x, ((x20)/x-28)=5/3 ,3 into 20)=5(into28),3 into 60 into =5 into =140,2=80,x=40
