Adam has stickers in 4 colours.
38 of the stickers are green.
The rest of the stickers are blue, yellow and red in the ratio of 1 : 5 : 8.
If there are 100 more yellow stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Yellow |
Red |
3 x 14 |
5 x 14 |
|
1 x 5 |
5 x 5 |
8 x 5 |
42 u |
5 u |
25 u |
40 u |
The number of green, blue and yellow stickers is the combined repeated identity.
Make the number of green, blue and yellow stickers the same using the LCM of 5 and 14.
LCM of 5 and 14 = 70
Number of more yellow stickers than blue stickers
= 25 u - 5 u
= 20 u
20 u = 100
1 u = 100 ÷ 20 = 5
Number of green stickers
= 42 u
= 42 x 5
= 210
Answer(s): 210
