A bakery made some sardine, beef and chicken croissants. For every 2 sardine croissants that were made, 1 chicken croissant were made. For every 8 sardine croissants that were made, 7 beef croissants were made.
- Find the ratio of the number of sardine croissants to beef croissants to chicken croissants made.
- After the bakery made another 57 chicken croissants, 25% of the croissants now were chicken croissants. How many sardine croissants did the bakery make?
(a)
Sardine |
Beef |
Chicken |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Sardine : Beef : Chicken
8 : 7 : 4
(b)
|
Sardine |
Beef |
Chicken |
Before |
15 u |
4 u |
Change |
No change |
+ 57 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of sardine and beef croissants
= 7 u + 8 u
= 15 u
Increase in the number of chicken croissants
= 5 u - 4 u
= 1 u
1 u = 57
Number of sardine croissants
= 8 u
= 8 x 57
= 456
Answer(s): (a) 8 : 7 : 4 ; (b) 456
