Adam has stickers in 4 colours.
49 of the stickers are green.
The rest of the stickers are blue, yellow and red in the ratio of 1 : 3 : 5.
If there are 70 more yellow stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Yellow |
Red |
4 x 9 |
5 x 9 |
|
1 x 5 |
3 x 5 |
5 x 5 |
36 u |
5 u |
15 u |
25 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 9.
LCM of 5 and 9 = 45
Number of more yellow stickers than blue stickers
= 15 u - 5 u
= 10 u
10 u = 70
1 u = 70 ÷ 10 = 7
Number of green stickers
= 36 u
= 36 x 7
= 252
Answer(s): 252
