Adam has stickers in 4 colours.
59 of the stickers are green.
The rest of the stickers are yellow, blue and red in the ratio of 1 : 2 : 7.
If there are 80 more blue stickers than yellow stickers,
how many green stickers are there?
Green |
Yellow |
Blue |
Red |
5 x 5 |
4 x 5 |
|
1 x 2 |
2 x 2 |
7 x 2 |
25 u |
2 u |
4 u |
14 u |
The number of green, yellow and blue stickers is the combined repeated identity.
Make the number of green, yellow and blue stickers the same using the LCM of 4 and 10.
LCM of 4 and 10 = 20
Number of more blue stickers than yellow stickers
= 4 u - 2 u
= 2 u
2 u = 80
1 u = 80 ÷ 2 = 40
Number of green stickers
= 25 u
= 25 x 40
= 1000
Answer(s): 1000
