Adam has stickers in 4 colours.
34 of the stickers are green.
The rest of the stickers are yellow, red and blue in the ratio of 2 : 4 : 3.
If there are 30 more red stickers than yellow stickers,
how many green stickers are there?
Green |
Yellow |
Red |
Blue |
3 x 9 |
1 x 9 |
|
2 x 1 |
4 x 1 |
3 x 1 |
27 u |
2 u |
4 u |
3 u |
The number of green, yellow and red stickers is the combined repeated identity.
Make the number of green, yellow and red stickers the same using the LCM of 1 and 9.
LCM of 1 and 9 = 9
Number of more red stickers than yellow stickers
= 4 u - 2 u
= 2 u
2 u = 30
1 u = 30 ÷ 2 = 15
Number of green stickers
= 27 u
= 27 x 15
= 405
Answer(s): 405
