Adam has stickers in 4 colours.
34 of the stickers are green.
The rest of the stickers are red, yellow and blue in the ratio of 3 : 5 : 5.
If there are 90 more yellow stickers than red stickers,
how many green stickers are there?
Green |
Red |
Yellow |
Blue |
3 x 13 |
1 x 13 |
|
3 x 1 |
5 x 1 |
5 x 1 |
39 u |
3 u |
5 u |
5 u |
The number of green, red and yellow stickers is the combined repeated identity.
Make the number of green, red and yellow stickers the same using the LCM of 1 and 13.
LCM of 1 and 13 = 13
Number of more yellow stickers than red stickers
= 5 u - 3 u
= 2 u
2 u = 90
1 u = 90 ÷ 2 = 45
Number of green stickers
= 39 u
= 39 x 45
= 1755
Answer(s): 1755
