What is \( \frac{4}{9} \) x \( \frac{4}{7} \)?
| 2\(\frac{2}{7}\) | |
| \(\frac{1}{14}\) | |
| \(\frac{1}{7}\) | |
| \(\frac{16}{63}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{9} \) x \( \frac{4}{7} \) = \( \frac{4 x 4}{9 x 7} \) = \( \frac{16}{63} \) = \(\frac{16}{63}\)

Frank loaned Jennifer $800 at an annual interest rate of 2%. If no payments are made, what is the total amount owed at the end of the first year?
| $848 | |
| $872 | |
| $840 | |
| $816 |
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 $800
i = 0.02 x $800
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $800 + $16April scored 76% on her final exam. If each question was worth 2 points and there were 140 possible points on the exam, how many questions did April answer correctly?
| 66 | |
| 53 | |
| 46 | |
| 42 |
April scored 76% on the test meaning she earned 76% of the possible points on the test. There were 140 possible points on the test so she earned 140 x 0.76 = 106 points. Each question is worth 2 points so she got \( \frac{106}{2} \) = 53 questions right.
Bob loaned Alex $900 at an annual interest rate of 9%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $6 | |
| $21 | |
| $81 | |
| $108 |
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 $900
i = 0.09 x $900
i = $81
