Answer:
25%
Step-by-step explanation:
Calculation for the proportion of Machining activity used by Product 5
Using this formula
Machining activity = Product 5 Machine hours /Total machine hours
Let plug in the formula
Machining activity = 1,100/4,400
Machining activity = 0.25×100
Machining activity = 25%
Therefore the proportion of Machining activity used by Product 5 is 25%
