There are 180 balls in Dana's collection. The number of her pink balls is 5 times the number of her yellow balls.
- How many yellow balls does she have?
- How many pink balls does she have?
(a)
Number of yellow balls = 1 u
Number of pink balls = 5 u
Total number of balls
= 1 u + 5 u
= 6 u
6 u = 180
1 u = 180 ÷ 6 = 30
Number of yellow balls
= 1 u
= 30
(b)
Number of pink balls
= 5 u
= 5 x 30
= 150
Answer(s): (a) 30; (b) 150
