Solve 21/2-(1/5)=

$$2 \frac{ 1 }{ 2 } -( \frac{ 1 }{ 5 } )=$$

Evaluate

$$\frac{23}{10}=2.3$$

Solution Steps

Multiply 2 and 2 to get 4.

$$\frac{4+1}{2}-\frac{1}{5}$$

Add 4 and 1 to get 5.

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

Least common multiple of 2 and 5 is 10. Convert \frac{5}{2} and \frac{1}{5} to fractions with denominator 10.

$$\frac{25}{10}-\frac{2}{10}$$

Since \frac{25}{10} and \frac{2}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{25-2}{10}$$

Subtract 2 from 25 to get 23.

$$\frac{23}{10}$$

Factor

$$\frac{23}{2 \cdot 5} = 2\frac{3}{10} = 2.3$$
