Adam has stickers in 4 colours.
38 of the stickers are green.
The rest of the stickers are blue, yellow and red in the ratio of 1 : 3 : 6.
If there are 140 more yellow stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Yellow |
Red |
3 x 2 |
5 x 2 |
|
1 x 1 |
3 x 1 |
6 x 1 |
6 u |
1 u |
3 u |
6 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 5 and 10.
LCM of 5 and 10 = 10
Number of more yellow stickers than blue stickers
= 3 u - 1 u
= 2 u
2 u = 140
1 u = 140 ÷ 2 = 70
Number of green stickers
= 6 u
= 6 x 70
= 420
Answer(s): 420
