A bakery made some chicken, beef and chocolate sandwiches. For every 2 chicken sandwiches that were made, 1 chocolate sandwich were made. For every 8 chicken sandwiches that were made, 7 beef sandwiches were made.
- Find the ratio of the number of chicken sandwiches to beef sandwiches to chocolate sandwiches made.
- After the bakery made another 80 chocolate sandwiches, 25% of the sandwiches now were chocolate sandwiches. How many chicken sandwiches did the bakery make?
(a)
Chicken |
Beef |
Chocolate |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Chicken : Beef : Chocolate
8 : 7 : 4
(b)
|
Chicken |
Beef |
Chocolate |
Before |
15 u |
4 u |
Change |
No change |
+ 80 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of chicken and beef sandwiches
= 7 u + 8 u
= 15 u
Increase in the number of chocolate sandwiches
= 5 u - 4 u
= 1 u
1 u = 80
Number of chicken sandwiches
= 8 u
= 8 x 80
= 640
Answer(s): (a) 8 : 7 : 4 ; (b) 640
