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
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 =)
