Adam has stickers in 4 colours.
79 of the stickers are yellow.
The rest of the stickers are blue, red and green in the ratio of 1 : 4 : 8.
If there are 60 more red stickers than blue stickers,
how many yellow stickers are there?
Yellow |
Blue |
Red |
Green |
7 x 13 |
2 x 13 |
|
1 x 2 |
4 x 2 |
8 x 2 |
91 u |
2 u |
8 u |
16 u |
The number of yellow, blue and red stickers is the combined repeated identity.
Make the number of yellow, blue and red stickers the same using the LCM of 2 and 13.
LCM of 2 and 13 = 26
Number of more red stickers than blue stickers
= 8 u - 2 u
= 6 u
6 u = 60
1 u = 60 ÷ 6 = 10
Number of yellow stickers
= 91 u
= 91 x 10
= 910
Answer(s): 910
