Adam has stickers in 4 colours.
38 of the stickers are yellow.
The rest of the stickers are blue, red and green in the ratio of 2 : 3 : 8.
If there are 110 more red stickers than blue stickers,
how many yellow stickers are there?
Yellow |
Blue |
Red |
Green |
3 x 13 |
5 x 13 |
|
2 x 5 |
3 x 5 |
8 x 5 |
39 u |
10 u |
15 u |
40 u |
The number of yellow, blue and red stickers is the combined repeated identity.
Make the number of yellow, blue and red stickers the same using the LCM of 5 and 13.
LCM of 5 and 13 = 65
Number of more red stickers than blue stickers
= 15 u - 10 u
= 5 u
5 u = 110
1 u = 110 ÷ 5 = 22
Number of yellow stickers
= 39 u
= 39 x 22
= 858
Answer(s): 858
