There are 252 balls in Linda's collection. The number of her white balls is 2 times the number of her brown balls.
- How many brown balls does she have?
- How many white balls does she have?
(a)
Number of brown balls = 1 u
Number of white balls = 2 u
Total number of balls
= 1 u + 2 u
= 3 u
3 u = 252
1 u = 252 ÷ 3 = 84
Number of brown balls
= 1 u
= 84
(b)
Number of white balls
= 2 u
= 2 x 84
= 168
Answer(s): (a) 84; (b) 168
