There are 168 balls in Cindy's collection. The number of her red balls is 5 times the number of her pink balls.
- How many pink balls does she have?
- How many red balls does she have?
(a)
Number of pink balls = 1 u
Number of red balls = 5 u
Total number of balls
= 1 u + 5 u
= 6 u
6 u = 168
1 u = 168 ÷ 6 = 28
Number of pink balls
= 1 u
= 28
(b)
Number of red balls
= 5 u
= 5 x 28
= 140
Answer(s): (a) 28; (b) 140
