There are 216 balls in Linda's collection. The number of her grey balls is 5 times the number of her blue balls.
- How many blue balls does she have?
- How many grey balls does she have?
(a)
Number of blue balls = 1 u
Number of grey balls = 5 u
Total number of balls
= 1 u + 5 u
= 6 u
6 u = 216
1 u = 216 ÷ 6 = 36
Number of blue balls
= 1 u
= 36
(b)
Number of grey balls
= 5 u
= 5 x 36
= 180
Answer(s): (a) 36; (b) 180
