A proportion is an equation that states that two ratios are equal. Let's analyze the two options provided:
-
5/6 = 17/18
- To check if these two fractions are equal, we can cross-multiply: \[ 5 \times 18 = 90 \] \[ 6 \times 17 = 102 \] Since 90 is not equal to 102, \( \frac{5}{6} \neq \frac{17}{18} \).
-
5/6 = 20/18
- Again, we'll cross-multiply: \[ 5 \times 18 = 90 \] \[ 6 \times 20 = 120 \] Since 90 is not equal to 120, \( \frac{5}{6} \neq \frac{20}{18} \).
Neither of the options given (5/6 = 17/18 or 5/6 = 20/18) represents a true proportion.
