Jenna has 3 red balloons and 5 blue balloons.
The ratio of the number of red balloons to the number of blue balloons is
3:5
She adds 2 red balloons and removes 1 blue balloon.
The new ratio of the number of red balloons to the number of blue balloons is
3+2:5-1
5:4
18/27
(2*9)/(3*9)
***cancel 9***
2/3
two thirds is the answer
You only did the last one wrong, (3/4) times 2 is 3/2. 3/2 - 1/2 is 2/2 or 1.
So it'd be (2,1)
