Solve 12/5-1/3

$$1 \frac { 2 } { 5 } - \frac { 1 } { 3 }$$

Evaluate

$$\frac{16}{15}\approx 1.066666667$$

Solution Steps

Multiply 1 and 5 to get 5.

$$\frac{5+2}{5}-\frac{1}{3}$$

Add 5 and 2 to get 7.

$$\frac{7}{5}-\frac{1}{3}$$

Least common multiple of 5 and 3 is 15. Convert \frac{7}{5} and \frac{1}{3} to fractions with denominator 15.

$$\frac{21}{15}-\frac{5}{15}$$

Since \frac{21}{15} and \frac{5}{15} have the same denominator, subtract them by subtracting their numerators.

$$\frac{21-5}{15}$$

Subtract 5 from 21 to get 16.

$$\frac{16}{15}$$

Factor

$$\frac{2 ^ {4}}{3 \cdot 5} = 1\frac{1}{15} = 1.0666666666666667$$
