Adam has stickers in 4 colours.
67 of the stickers are yellow.
The rest of the stickers are red, green and blue in the ratio of 2 : 4 : 3.
If there are 10 more green stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Green |
Blue |
6 x 9 |
1 x 9 |
|
2 x 1 |
4 x 1 |
3 x 1 |
54 u |
2 u |
4 u |
3 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
= 4 u - 2 u
= 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of yellow stickers
= 54 u
= 54 x 5
= 270
Answer(s): 270
