What is \( \frac{2}{7} \) x \( \frac{3}{6} \)?
| \(\frac{1}{18}\) | |
| \(\frac{6}{49}\) | |
| 1 | |
| \(\frac{1}{7}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{2}{7} \) x \( \frac{3}{6} \) = \( \frac{2 x 3}{7 x 6} \) = \( \frac{6}{42} \) = \(\frac{1}{7}\)

Solve 4 + (2 + 3) ÷ 5 x 5 - 32
| 1 | |
| 1\(\frac{1}{3}\) | |
| 1\(\frac{1}{4}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
4 + (2 + 3) ÷ 5 x 5 - 32
P: 4 + (5) ÷ 5 x 5 - 32
E: 4 + 5 ÷ 5 x 5 - 9
MD: 4 + \( \frac{5}{5} \) x 5 - 9
MD: 4 + \( \frac{25}{5} \) - 9
AS: \( \frac{20}{5} \) + \( \frac{25}{5} \) - 9
AS: \( \frac{45}{5} \) - 9
AS: \( \frac{45 - 45}{5} \)
\( \frac{0}{5} \)
