There are 210 balls in Yoko's collection. The number of her gold balls is 6 times the number of her silver balls.
- How many silver balls does she have?
- How many gold balls does she have?
(a)
Number of silver balls = 1 u
Number of gold balls = 6 u
Total number of balls
= 1 u + 6 u
= 7 u
7 u = 210
1 u = 210 ÷ 7 = 30
Number of silver balls
= 1 u
= 30
(b)
Number of gold balls
= 6 u
= 6 x 30
= 180
Answer(s): (a) 30; (b) 180
