Solve 13/5-11/2=

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

Evaluate

$$\frac{1}{10}=0.1$$

Solution Steps

Multiply 1 and 5 to get 5.

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

Add 5 and 3 to get 8.

$$\frac{8}{5}-\frac{1\times 2+1}{2}$$

Multiply 1 and 2 to get 2.

$$\frac{8}{5}-\frac{2+1}{2}$$

Add 2 and 1 to get 3.

$$\frac{8}{5}-\frac{3}{2}$$

Least common multiple of 5 and 2 is 10. Convert \frac{8}{5} and \frac{3}{2} to fractions with denominator 10.

$$\frac{16}{10}-\frac{15}{10}$$

Since \frac{16}{10} and \frac{15}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{16-15}{10}$$

Subtract 15 from 16 to get 1.

$$\frac{1}{10}$$

Factor

$$\frac{1}{2 \cdot 5} = 0.1$$
