Adam has stickers in 4 colours.
34 of the stickers are yellow.
The rest of the stickers are red, green and blue in the ratio of 1 : 3 : 5.
If there are 100 more green stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Green |
Blue |
3 x 9 |
1 x 9 |
|
1 x 1 |
3 x 1 |
5 x 1 |
27 u |
1 u |
3 u |
5 u |
The number of yellow, red and green stickers is the combined repeated identity.
Make the number of yellow, red and green stickers the same using the LCM of 1 and 9.
LCM of 1 and 9 = 9
Number of more green stickers than red stickers
= 3 u - 1 u
= 2 u
2 u = 100
1 u = 100 ÷ 2 = 50
Number of yellow stickers
= 27 u
= 27 x 50
= 1350
Answer(s): 1350
