Solve 11/2-7/10

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

Evaluate

$$\frac{4}{5}=0.8$$

Solution Steps

Multiply 1 and 2 to get 2.

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

Add 2 and 1 to get 3.

$$\frac{3}{2}-\frac{7}{10}$$

Least common multiple of 2 and 10 is 10. Convert \frac{3}{2} and \frac{7}{10} to fractions with denominator 10.

$$\frac{15}{10}-\frac{7}{10}$$

Since \frac{15}{10} and \frac{7}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{15-7}{10}$$

Subtract 7 from 15 to get 8.

$$\frac{8}{10}$$

Reduce the fraction \frac{8}{10} to lowest terms by extracting and canceling out 2.

$$\frac{4}{5}$$

Factor

$$\frac{2 ^ {2}}{5} = 0.8$$
