Adam has stickers in 4 colours.
27 of the stickers are green.
The rest of the stickers are blue, red and yellow in the ratio of 1 : 3 : 3.
If there are 100 more red stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Red |
Yellow |
2 x 7 |
5 x 7 |
|
1 x 5 |
3 x 5 |
3 x 5 |
14 u |
5 u |
15 u |
15 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 7.
LCM of 5 and 7 = 35
Number of more red stickers than blue stickers
= 15 u - 5 u
= 10 u
10 u = 100
1 u = 100 ÷ 10 = 10
Number of green stickers
= 14 u
= 14 x 10
= 140
Answer(s): 140
