Edward had 45 water bottles. If he drank 1/9 of water bottles, how many did he drank?

Helen [10]

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:

$\frac{1}{9}*45$

$=\frac{45*1}{9}$ Combine into numerator (top) to multiply

$=\frac{45}{9}$ Simplify the fraction by dividing top by bottom

$=5$ Answer

Therefore, Edward drank 5 water bottles.
