a bag of flour contains 8 cups of flour a batch of cookies requires 1 2/5 cups of flour how many batches of cookies can you make with a bag of flour

Put 8 into fraction form: 8/1

Put 1 2/5 into a mixed number: 1*5+2 as numerator and 5 as denominator (7/5)

Now multiply 8/1 by the reciprocal of 7/5, which is basically just the numerator and denominator flipped, so 5/7. This is like dividing.

8/1*5/7 = 40/7

40/7 = about 5.7.

So, your answer would be 5.7 batches, or 5 complete batches would be a better answer.
