Answer:
He drank 5 water bottles.
Step-by-step explanation:
We need to find one-ninth (1/9) of the total number of water bottles (45).
Multiply the two numbers together:
[tex]\frac{1}{9}*45[/tex]
[tex]=\frac{45*1}{9}[/tex] Combine into numerator (top) to multiply
[tex]=\frac{45}{9}[/tex] Simplify the fraction by dividing top by bottom
[tex]=5[/tex] Answer
Therefore, Edward drank 5 water bottles.
