Adam has stickers in 4 colours.
79 of the stickers are yellow.
The rest of the stickers are red, green and blue in the ratio of 1 : 2 : 6.
If there are 140 more green stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Green |
Blue |
7 x 9 |
2 x 9 |
|
1 x 2 |
2 x 2 |
6 x 2 |
63 u |
2 u |
4 u |
12 u |
The number of yellow, red and green stickers is the combined repeated identity.
Make the number of yellow, red and green stickers the same using the LCM of 2 and 9.
LCM of 2 and 9 = 18
Number of more green stickers than red stickers
= 4 u - 2 u
= 2 u
2 u = 140
1 u = 140 ÷ 2 = 70
Number of yellow stickers
= 63 u
= 63 x 70
= 4410
Answer(s): 4410
