I think it's 30 because you have to divide 12 by 40 and multiply the answer by 100.

Johnny Mullen · Answer 2

Here, we need to set up a proportion.

40/12 = 100/x

Cross multiply.

40*x = 40x

100*12 = 1200

40x = 1200

40x/40 = 1200/40

x = 1200/40

x = 30

Final answer: It will take 30 minutes to weave 100 inches of fabric.
