Solve 2quad1/2-7/10=

$$2 \quad \frac { 1 } { 2 } - \frac { 7 } { 10 } =$$

Evaluate

$$\frac{9}{5}=1.8$$

Solution Steps

Multiply 2 and 2 to get 4.

$$\frac{4+1}{2}-\frac{7}{10}$$

Add 4 and 1 to get 5.

$$\frac{5}{2}-\frac{7}{10}$$

Least common multiple of 2 and 10 is 10. Convert \frac{5}{2} and \frac{7}{10} to fractions with denominator 10.

$$\frac{25}{10}-\frac{7}{10}$$

Since \frac{25}{10} and \frac{7}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{25-7}{10}$$

Subtract 7 from 25 to get 18.

$$\frac{18}{10}$$

Reduce the fraction \frac{18}{10} to lowest terms by extracting and canceling out 2.

$$\frac{9}{5}$$

Factor

$$\frac{3 ^ {2}}{5} = 1\frac{4}{5} = 1.8$$
