Stephens glass holds 450 milliliters of milk. Naiahs glass holds 2/5 as much milk. How much does Naiahs glass hold?

Well there is 450 millimeters in general and Naiahs glass hold 2 out of the five fifths of Stephens glass. so you have to do 450 divided by 5 which is 90. but that is only one fifth, you have to do 90 times two. so it would be 180 millimeters. 180/450.
