Adam has stickers in 4 colours.
710 of the stickers are green.
The rest of the stickers are blue, yellow and red in the ratio of 1 : 3 : 5.
If there are 10 more yellow stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Yellow |
Red |
7 x 3 |
3 x 3 |
|
1 x 1 |
3 x 1 |
5 x 1 |
21 u |
1 u |
3 u |
5 u |
The number of green, blue and yellow stickers is the combined repeated identity.
Make the number of green, blue and yellow stickers the same using the LCM of 3 and 9.
LCM of 3 and 9 = 9
Number of more yellow stickers than blue stickers
= 3 u - 1 u
= 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of green stickers
= 21 u
= 21 x 5
= 105
Answer(s): 105
