Solve 12/8-13/4

$$1 \frac{ 2 }{ 8 } -1 \frac{ 3 }{ 4 }$$

Evaluate

$$-\frac{1}{2}=-0.5$$

Solution Steps

Multiply 1 and 8 to get 8.

$$\frac{8+2}{8}-\frac{1\times 4+3}{4}$$

Add 8 and 2 to get 10.

$$\frac{10}{8}-\frac{1\times 4+3}{4}$$

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

$$\frac{5}{4}-\frac{1\times 4+3}{4}$$

Multiply 1 and 4 to get 4.

$$\frac{5}{4}-\frac{4+3}{4}$$

Add 4 and 3 to get 7.

$$\frac{5}{4}-\frac{7}{4}$$

Since \frac{5}{4} and \frac{7}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-7}{4}$$

Subtract 7 from 5 to get -2.

$$\frac{-2}{4}$$

Reduce the fraction \frac{-2}{4} to lowest terms by extracting and canceling out 2.

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

Factor

$$-\frac{1}{2} = -0.5$$
