$$3 \frac{ 1 }{ 3 } -2.5$$

Evaluate

$$\frac{5}{6}\approx 0.833333333$$

Solution Steps

Multiply 3 and 3 to get 9.

$$\frac{9+1}{3}-2.5$$

Add 9 and 1 to get 10.

$$\frac{10}{3}-2.5$$

Convert decimal number 2.5 to fraction \frac{25}{10}. Reduce the fraction \frac{25}{10} to lowest terms by extracting and canceling out 5.

$$\frac{10}{3}-\frac{5}{2}$$

Least common multiple of 3 and 2 is 6. Convert \frac{10}{3} and \frac{5}{2} to fractions with denominator 6.

$$\frac{20}{6}-\frac{15}{6}$$

Since \frac{20}{6} and \frac{15}{6} have the same denominator, subtract them by subtracting their numerators.

$$\frac{20-15}{6}$$

Subtract 15 from 20 to get 5.

$$\frac{5}{6}$$

Factor

$$\frac{5}{2 \cdot 3} = 0.8333333333333334$$
