Answer:
20 bikes.
Step-by-step explanation:
25 frames with 40 tires?
Well if there are 2 tires per frame then you can just divide 40 into 2 to make it easier.
40/2=20
So now you have 20 sets of tires. and 1 set goes to 1 frame.
25 - 20 = 5
so you have 5 frames left with no tires to add.
meaning you can only make 20 bikes :)
