Adam has stickers in 4 colours.
78 of the stickers are blue.
The rest of the stickers are red, green and yellow in the ratio of 3 : 5 : 6.
If there are 60 more green stickers than red stickers,
how many blue stickers are there?
Blue |
Red |
Green |
Yellow |
7 x 14 |
1 x 14 |
|
3 x 1 |
5 x 1 |
6 x 1 |
98 u |
3 u |
5 u |
6 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 1 and 14.
LCM of 1 and 14 = 14
Number of more green stickers than red stickers
= 5 u - 3 u
= 2 u
2 u = 60
1 u = 60 ÷ 2 = 30
Number of blue stickers
= 98 u
= 98 x 30
= 2940
Answer(s): 2940
