Solve (1/2)*(9/3)-(8/7-1/7)=

$$( 1 / 2 ) * ( 9 / 3 ) - ( 8 / 7 - 1 / 7 ) =$$

Evaluate

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

Solution Steps

Divide 9 by 3 to get 3.

$$\frac{1}{2}\times 3-\left(\frac{8}{7}-\frac{1}{7}\right)$$

Multiply \frac{1}{2} and 3 to get \frac{3}{2}.

$$\frac{3}{2}-\left(\frac{8}{7}-\frac{1}{7}\right)$$

Since \frac{8}{7} and \frac{1}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{3}{2}-\frac{8-1}{7}$$

Subtract 1 from 8 to get 7.

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

Divide 7 by 7 to get 1.

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

Convert 1 to fraction \frac{2}{2}.

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

Since \frac{3}{2} and \frac{2}{2} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 2 from 3 to get 1.

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

Factor

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