Hello! :)

Use a proportion to find how many seconds are needed to fold 5 shirts.
We are given that he takes 28 seconds to fold 2 shirts:
28 sec : 2 shirts
We are not given the amount of time needed for 5 shirts, which we need to solve:
x seconds : 5 shirts
Express in a fraction:

Cross multiply and simplify:

Therefore, he needs 70 seconds to fold 5 shirts.
127 boxes is the answer
You just divide the number of eggs by 12
I don’t know if this is what you were asking because the question is worded weirdly
