Adam has stickers in 4 colours.
710 of the stickers are blue.
The rest of the stickers are red, green and yellow in the ratio of 2 : 3 : 3.
If there are 60 more green stickers than red stickers,
how many blue stickers are there?
Blue |
Red |
Green |
Yellow |
7 x 8 |
3 x 8 |
|
2 x 3 |
3 x 3 |
3 x 3 |
56 u |
6 u |
9 u |
9 u |
The number of blue, red and green stickers is the combined repeated identity.
Make the number of blue, red and green stickers the same using the LCM of 3 and 8.
LCM of 3 and 8 = 24
Number of more green stickers than red stickers
= 9 u - 6 u
= 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Number of blue stickers
= 56 u
= 56 x 20
= 1120
Answer(s): 1120
