Adam has stickers in 4 colours.
59 of the stickers are red.
The rest of the stickers are green, yellow and blue in the ratio of 3 : 4 : 6.
If there are 80 more yellow stickers than green stickers,
how many red stickers are there?
Red |
Green |
Yellow |
Blue |
5 x 13 |
4 x 13 |
|
3 x 4 |
4 x 4 |
6 x 4 |
65 u |
12 u |
16 u |
24 u |
The number of red, green and yellow stickers is the combined repeated identity.
Make the number of red, green and yellow stickers the same using the LCM of 4 and 13.
LCM of 4 and 13 = 52
Number of more yellow stickers than green stickers
= 16 u - 12 u
= 4 u
4 u = 80
1 u = 80 ÷ 4 = 20
Number of red stickers
= 65 u
= 65 x 20
= 1300
Answer(s): 1300
