Adam has stickers in 4 colours.
56 of the stickers are blue.
The rest of the stickers are red, yellow and green in the ratio of 1 : 5 : 8.
If there are 60 more yellow stickers than red stickers,
how many blue stickers are there?
Blue |
Red |
Yellow |
Green |
5 x 14 |
1 x 14 |
|
1 x 1 |
5 x 1 |
8 x 1 |
70 u |
1 u |
5 u |
8 u |
The number of blue, red and yellow stickers is the combined repeated identity.
Make the number of blue, red and yellow stickers the same using the LCM of 1 and 14.
LCM of 1 and 14 = 14
Number of more yellow stickers than red stickers
= 5 u - 1 u
= 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of blue stickers
= 70 u
= 70 x 15
= 1050
Answer(s): 1050
