Answer:
b) three full bottles of water.
Step-by-step explanation:
According to a different source, these are the options that come with this question:
a) two full bottles of water.
b) three full bottles of water.
c) nine full bottles of water.
d) twelve full bottles of water.
In this question, we see that the professor walked into class today with six bottles of water. However, each one of this was half-full.
A half-full bottle would be represented in the following way as a fraction: 1/2
However, the professor walked in with six of these half bottles, therefore:
1/2 (6) = 6/2
If we were to simplify this fraction (by dividing the quantities by two) we would get:
6/2 = 3/1
Which means that six half-full bottles equals three full bottles of water.
