Solve 36-4div8-4/4*8-2*16+1

$$\frac{ 36-4 \div 8-4 }{ 4 \cdot 8-2 \cdot 16+1 }$$

Evaluate

$$\frac{63}{2}=31.5$$

Solution Steps

Reduce the fraction \frac{4}{8} to lowest terms by extracting and canceling out 4.

$$\frac{36-\frac{1}{2}-4}{4\times 8-2\times 16+1}$$

Convert 36 to fraction \frac{72}{2}.

$$\frac{\frac{72}{2}-\frac{1}{2}-4}{4\times 8-2\times 16+1}$$

Since \frac{72}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{\frac{72-1}{2}-4}{4\times 8-2\times 16+1}$$

Subtract 1 from 72 to get 71.

$$\frac{\frac{71}{2}-4}{4\times 8-2\times 16+1}$$

Convert 4 to fraction \frac{8}{2}.

$$\frac{\frac{71}{2}-\frac{8}{2}}{4\times 8-2\times 16+1}$$

Since \frac{71}{2} and \frac{8}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{\frac{71-8}{2}}{4\times 8-2\times 16+1}$$

Subtract 8 from 71 to get 63.

$$\frac{\frac{63}{2}}{4\times 8-2\times 16+1}$$

Multiply 4 and 8 to get 32.

$$\frac{\frac{63}{2}}{32-2\times 16+1}$$

Multiply 2 and 16 to get 32.

$$\frac{\frac{63}{2}}{32-32+1}$$

Subtract 32 from 32 to get 0.

$$\frac{\frac{63}{2}}{0+1}$$

Add 0 and 1 to get 1.

$$\frac{\frac{63}{2}}{1}$$

Anything divided by one gives itself.

$$\frac{63}{2}$$

Factor

$$\frac{3 ^ {2} \cdot 7}{2} = 31\frac{1}{2} = 31.5$$
