Adam has stickers in 4 colours.
79 of the stickers are green.
The rest of the stickers are red, yellow and blue in the ratio of 1 : 3 : 4.
If there are 70 more yellow stickers than red stickers,
how many green stickers are there?
Green |
Red |
Yellow |
Blue |
7 x 4 |
2 x 4 |
|
1 x 1 |
3 x 1 |
4 x 1 |
28 u |
1 u |
3 u |
4 u |
The number of green, red and yellow stickers is the combined repeated identity.
Make the number of green, red and yellow stickers the same using the LCM of 2 and 8.
LCM of 2 and 8 = 8
Number of more yellow stickers than red stickers
= 3 u - 1 u
= 2 u
2 u = 70
1 u = 70 ÷ 2 = 35
Number of green stickers
= 28 u
= 28 x 35
= 980
Answer(s): 980
