There are 260 balls in Linda's collection. The number of her brown balls is 4 times the number of her grey balls.
- How many grey balls does she have?
- How many brown balls does she have?
(a)
Number of grey balls = 1 u
Number of brown balls = 4 u
Total number of balls
= 1 u + 4 u
= 5 u
5 u = 260
1 u = 260 ÷ 5 = 52
Number of grey balls
= 1 u
= 52
(b)
Number of brown balls
= 4 u
= 4 x 52
= 208
Answer(s): (a) 52; (b) 208
