The ratio of the number of Aaliyah’s pens to the number of Mariah’s pens was 2:3 at first. After Dad gave Aaliyah another 16 pens, the ratio became 2:1.

Answer:

(2x + 16)/3x = 2/1

2x + 16 = 6x

4x = 16

x = 4

Aaliyah's pens = 2x = 2 × 4 = 8

the number of Maria's pen = 3x = 3 × 4 = 12 -----Part A

New ratio = (8 + 16)/6

24/6 = 4/1 = 4 : 1 --------- Part B Explanation:
