Adam has stickers in 4 colours.
49 of the stickers are yellow.
The rest of the stickers are red, green and blue in the ratio of 2 : 3 : 9.
If there are 110 more green stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Green |
Blue |
4 x 14 |
5 x 14 |
|
2 x 5 |
3 x 5 |
9 x 5 |
56 u |
10 u |
15 u |
45 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 5 and 14.
LCM of 5 and 14 = 70
Number of more green stickers than red stickers
= 15 u - 10 u
= 5 u
5 u = 110
1 u = 110 ÷ 5 = 22
Number of yellow stickers
= 56 u
= 56 x 22
= 1232
Answer(s): 1232
