Question

Trey has completed 36 deliveries so far this week. He needs to make 80 deliveries for the week. What percentage of deliveries has trey completed?

Answer 1

We must build the proportion

deliveries made : deliveries due = x : 100

in fact, we must express the fraction of work done as a fraction with denominator 100.

So, we have

$\dfrac{36}{80}=\dfrac{x}{100}\iff x=\dfrac{3600}{80}=45$

Trey has completed 45% of his work so far.
