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 : 3.
If there are 60 more yellow stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Yellow |
Red |
4 x 7 |
5 x 7 |
|
1 x 5 |
3 x 5 |
3 x 5 |
28 u |
5 u |
15 u |
15 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 7.
LCM of 5 and 7 = 35
Number of more yellow stickers than blue stickers
= 15 u - 5 u
= 10 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of green stickers
= 28 u
= 28 x 6
= 168
Answer(s): 168
