A bakery made some sardine, egg and chicken sandwiches. For every 2 sardine sandwiches that were made, 1 chicken sandwich were made. For every 8 sardine sandwiches that were made, 7 egg sandwiches were made.
- Find the ratio of the number of sardine sandwiches to egg sandwiches to chicken sandwiches made.
- After the bakery made another 60 chicken sandwiches, 25% of the sandwiches now were chicken sandwiches. How many sardine sandwiches did the bakery make?
(a)

1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Sardine : Egg : Chicken
8 : 7 : 4
(b)

Sardine |
Egg |
Chicken |
Before |

No change |
+ 60 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of sardine and egg sandwiches
= 7 u + 8 u
= 15 u
Increase in the number of chicken sandwiches
= 5 u - 4 u
= 1 u
1 u = 60
Number of sardine sandwiches
= 8 u
= 8 x 60
= 480
Answer(s): (a) 8 : 7 : 4 ; (b) 480
