Answer 2

Answer:

Problems left to complete = 9

Step-by-step explanation:

Given that:

Number of problems on the test = 45

Percent of completed problems = 80%

Number of completed problems = $\frac{80}{100}*45$

Number of completed problems = 0.8 * 45 = 36

Problems left to complete = 45 - 36

Problems left  = 9

Hence,

Problems left to complete = 9
