Solve 28/3-15/4

$$\frac { 28 } { 3 } - \frac { 15 } { 4 }$$

Evaluate

$$\frac{67}{12}\approx 5.583333333$$

Solution Steps

Least common multiple of 3 and 4 is 12. Convert \frac{28}{3} and \frac{15}{4} to fractions with denominator 12.

$$\frac{112}{12}-\frac{45}{12}$$

Since \frac{112}{12} and \frac{45}{12} have the same denominator, subtract them by subtracting their numerators.

Subtract 45 from 112 to get 67.

$$\frac{67}{12}$$

Factor

$$\frac{67}{2 ^ {2} \cdot 3} = 5\frac{7}{12} = 5.583333333333333$$
