Adam has stickers in 4 colours.
38 of the stickers are yellow.
The rest of the stickers are green, red and blue in the ratio of 2 : 3 : 4.
If there are 10 more red stickers than green stickers,
how many yellow stickers are there?
Yellow |
Green |
Red |
Blue |
3 x 9 |
5 x 9 |
|
2 x 5 |
3 x 5 |
4 x 5 |
27 u |
10 u |
15 u |
20 u |
The number of yellow, green and red stickers is the combined repeated identity.
Make the number of yellow, green and red stickers the same using the LCM of 5 and 9.
LCM of 5 and 9 = 45
Number of more red stickers than green stickers
= 15 u - 10 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Number of yellow stickers
= 27 u
= 27 x 2
= 54
Answer(s): 54
