What is \( \frac{3}{7} \) ÷ \( \frac{1}{5} \)?
| \(\frac{1}{63}\) | |
| 15 | |
| \(\frac{2}{21}\) | |
| 2\(\frac{1}{7}\) |
To divide fractions, invert the second fraction and then multiply:
\( \frac{3}{7} \) ÷ \( \frac{1}{5} \) = \( \frac{3}{7} \) x \( \frac{5}{1} \)
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{7} \) x \( \frac{5}{1} \) = \( \frac{3 x 5}{7 x 1} \) = \( \frac{15}{7} \) = 2\(\frac{1}{7}\)
What is \( \frac{6\sqrt{18}}{3\sqrt{6}} \)?
| 2 \( \sqrt{3} \) | |
| \(\frac{1}{3}\) \( \sqrt{2} \) | |
| \(\frac{1}{2}\) \( \sqrt{\frac{1}{3}} \) | |
| \(\frac{1}{2}\) \( \sqrt{3} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{6\sqrt{18}}{3\sqrt{6}} \)
\( \frac{6}{3} \) \( \sqrt{\frac{18}{6}} \)
2 \( \sqrt{3} \)
A bread recipe calls for 2\(\frac{5}{8}\) cups of flour. If you only have \(\frac{1}{2}\) cup, how much more flour is needed?
| 2\(\frac{5}{8}\) cups | |
| 3\(\frac{1}{8}\) cups | |
| 1\(\frac{3}{4}\) cups | |
| 2\(\frac{1}{8}\) cups |
The amount of flour you need is (2\(\frac{5}{8}\) - \(\frac{1}{2}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{21}{8} \) - \( \frac{4}{8} \)) cups
\( \frac{17}{8} \) cups
2\(\frac{1}{8}\) cups
Roger loaned Latoya $1,000 at an annual interest rate of 9%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,030 | |
| $1,090 | |
| $1,050 | |
| $1,010 |
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 $1,000
i = 0.09 x $1,000
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,000 + $90Damon loaned Monty $900 at an annual interest rate of 6%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $90 | |
| $12 | |
| $54 | |
| $56 |
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 = 0.06 x $900
i = $54
