Adam has stickers in 4 colours.
49 of the stickers are yellow.
The rest of the stickers are green, blue and red in the ratio of 2 : 3 : 6.
If there are 10 more blue stickers than green stickers,
how many yellow stickers are there?
Yellow |
Green |
Blue |
Red |
4 x 11 |
5 x 11 |
|
2 x 5 |
3 x 5 |
6 x 5 |
44 u |
10 u |
15 u |
30 u |
The number of yellow, green and blue stickers is the combined repeated identity.
Make the number of yellow, green and blue stickers the same using the LCM of 5 and 11.
LCM of 5 and 11 = 55
Number of more blue stickers than green stickers
= 15 u - 10 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Number of yellow stickers
= 44 u
= 44 x 2
= 88
Answer(s): 88
