Anna earned 22 points on her last test. If there were 40 possible points, what was her percent grade?

dimulka [17.4K]

Answer:

55%

Step-by-step explanation:

Since Anna earned 22 points, and there was a total of 40 points, this means that she scored 22 out of 40 points. You can simplify this by dividing the denominator and numerator by 2. Then, you can multiply both the numerator and denominator by 5 to get a number out of 100.

$\frac{22}{40} = \frac{11}{20}=\frac{55}{100}*100%=55%$
