A customer placed an order for muffins.The Baker has completed 37.5% of the order after baking 81 muffins. How many muffins did
IceJOKER [234]
81 divided by 37.5 equals 2.16, 2.16 would be equivalent to 1% so to find 100% we simbly multiply 2.16 by 100, 2.16 multiplied by 100 equates to 216, so the Baker is making 216 muffins.

If this is a word problem, put it into your own words in case of getting in trouble.

I hope this helped, have an awesome day!!
