A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 10% off." If Bob buys two shirts, each with a regular price of $17, how much money will he save?
| $8.50 | |
| $4.25 | |
| $1.70 | |
| $0.85 |
By buying two shirts, Bob will save $17 x \( \frac{10}{100} \) = \( \frac{$17 x 10}{100} \) = \( \frac{$170}{100} \) = $1.70 on the second shirt.

Solve 5 + (4 + 3) ÷ 2 x 5 - 52
| 1\(\frac{1}{5}\) | |
| \(\frac{6}{7}\) | |
| -2\(\frac{1}{2}\) | |
| 1 |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
5 + (4 + 3) ÷ 2 x 5 - 52
P: 5 + (7) ÷ 2 x 5 - 52
E: 5 + 7 ÷ 2 x 5 - 25
MD: 5 + \( \frac{7}{2} \) x 5 - 25
MD: 5 + \( \frac{35}{2} \) - 25
AS: \( \frac{10}{2} \) + \( \frac{35}{2} \) - 25
AS: \( \frac{45}{2} \) - 25
AS: \( \frac{45 - 50}{2} \)
\( \frac{-5}{2} \)
-2\(\frac{1}{2}\)
What is \( \frac{4}{6} \) x \( \frac{3}{9} \)?
| 1\(\frac{1}{3}\) | |
| \(\frac{2}{9}\) | |
| \(\frac{1}{72}\) | |
| \(\frac{2}{5}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{6} \) x \( \frac{3}{9} \) = \( \frac{4 x 3}{6 x 9} \) = \( \frac{12}{54} \) = \(\frac{2}{9}\)
