b. \( \frac{3}{2}-\frac{5}{6}= \)

To solve \( \frac{3}{2} - \frac{5}{6} \), first find a common denominator. The least common multiple of 2 and 6 is 6. Rewrite \( \frac{3}{2} \) as \( \frac{9}{6} \) (by multiplying the numerator and denominator by 3). Now you can subtract: \( \frac{9}{6} - \frac{5}{6} = \frac{4}{6} \). Simplifying gives \( \frac{2}{3} \). Another trick for subtraction is to convert fractions to decimals. For instance, \( \frac{3}{2} = 1.5 \) and \( \frac{5}{6} \approx 0.833\). Subtracting those gives roughly \( 1.5 - 0.833 = 0.667 \), which is approximately \( \frac{2}{3} \) when converted back—making your life a whole lot easier!
