Adam has stickers in 4 colours.
710 of the stickers are green.
The rest of the stickers are yellow, blue and red in the ratio of 3 : 5 : 8.
If there are 30 more blue stickers than yellow stickers,
how many green stickers are there?
Green |
Yellow |
Blue |
Red |
7 x 16 |
3 x 16 |
|
3 x 3 |
5 x 3 |
8 x 3 |
112 u |
9 u |
15 u |
24 u |
The number of green, yellow and blue stickers is the combined repeated identity.
Make the number of green, yellow and blue stickers the same using the LCM of 3 and 16.
LCM of 3 and 16 = 48
Number of more blue stickers than yellow stickers
= 15 u - 9 u
= 6 u
6 u = 30
1 u = 30 ÷ 6 = 5
Number of green stickers
= 112 u
= 112 x 5
= 560
Answer(s): 560
