To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:

\( \sqrt{\frac{49}{49}} \)
\( \frac{\sqrt{49}}{\sqrt{49}} \)
\( \frac{\sqrt{7^2}}{\sqrt{7^2}} \)

A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.

Jennifer scored 96% on the test meaning she earned 96% of the possible points on the test. There were 240 possible points on the test so she earned 240 x 0.96 = 231 points. Each question is worth 3 points so she got \( \frac{231}{3} \) = 77 questions right.

The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:

interest = annual interest rate x loan amount

i = (\( \frac{6}{100} \)) x $1,100
i = 0.04 x $1,100

No payments were made so the total amount due is the original amount + the accumulated interest:

If 38% of the town's 45,000 voters cast ballots the number of votes cast is:

(\( \frac{38}{100} \)) x 45,000 = \( \frac{1,710,000}{100} \) = 17,100

The mayor got 56% of the votes cast which is:

(\( \frac{56}{100} \)) x 17,100 = \( \frac{957,600}{100} \) = 9,576 votes.
