Adam has stickers in 4 colours.
38 of the stickers are green.
The rest of the stickers are blue, red and yellow in the ratio of 1 : 3 : 7.
If there are 60 more red stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Red |
Yellow |
3 x 11 |
5 x 11 |
|
1 x 5 |
3 x 5 |
7 x 5 |
33 u |
5 u |
15 u |
35 u |
The number of green, blue and red stickers is the combined repeated identity.
Make the number of green, blue and red stickers the same using the LCM of 5 and 11.
LCM of 5 and 11 = 55
Number of more red stickers than blue stickers
= 15 u - 5 u
= 10 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of green stickers
= 33 u
= 33 x 6
= 198
Answer(s): 198
