Question

Joel made egg sandwiches and tuna sandwiches in the rAtio do 2:3. He then made 15 tuna sandwiches and the rating changed to 1:3. How many sandwiches did Joel make in all

Answer 1

Explanation:

15 divided by 3 = 5

5 x 2 = 10

10 + 15 + 15 = 40

The answer is 40

Answer 2

He made 45 sandwiches.
The ratio of tuna sandwiches never changed, therefore he made the same amount (15) both times.
2/3 of 15 is 10.
1/3 of 15 is 5.
5 + 10 + 15 + 15 = 45.
Hope that helped =)
