Adam has stickers in 4 colours.
27 of the stickers are green.
The rest of the stickers are red, blue and yellow in the ratio of 1 : 2 : 5.
If there are 60 more blue stickers than red stickers,
how many green stickers are there?
Green |
Red |
Blue |
Yellow |
2 x 8 |
5 x 8 |
|
1 x 5 |
2 x 5 |
5 x 5 |
16 u |
5 u |
10 u |
25 u |
The number of green, red and blue stickers is the combined repeated identity.
Make the number of green, red and blue stickers the same using the LCM of 5 and 8.
LCM of 5 and 8 = 40
Number of more blue stickers than red stickers
= 10 u - 5 u
= 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Number of green stickers
= 16 u
= 16 x 12
= 192
Answer(s): 192
