Answer :
90 dL times L/dL equals 9 L
How to find 90 dL times L/dL
To understand why 90 dL times L/dL equals 90L, it's important to understand the units involved and how they cancel out.
First, dL stands for deciliter, which is a unit of volume equal to one-tenth of a liter.
L, on the other hand, stands for liter, which is a unit of volume equal to 1000 milliliters or one cubic decimeter.
So, 90 dL represents a volume of 90 deciliters, while L/dL represents a ratio of liters to deciliters.
Specifically, L/dL means "liters per deciliter," which is a way of expressing a conversion factor between liters and deciliters.
Multiplying 90 dL by L/dL involves multiplying 90 dL by the conversion factor of L/dL, which is 1 liter per 10 deciliters. The deciliter units cancel out, leaving only the liter units.
Therefore, we can rewrite the calculation as follows:
90 dL x (1 L/10 dL) = (90/10) L = 9 L
So, the result is 9 L, which is equivalent to 90 dL times L/dL.
