Solve 32div8+45*12.5%+43*1/8

$$32 \div 8 + 45 \times 12.5 \% + 43 \times \frac { 1 } { 8 }$$

Evaluate

$$15$$

Solution Steps

Divide 32 by 8 to get 4.

$$4+45\times \frac{12.5}{100}+43\times \frac{1}{8}$$

Expand \frac{12.5}{100} by multiplying both numerator and the denominator by 10.

$$4+45\times \frac{125}{1000}+43\times \frac{1}{8}$$

Reduce the fraction \frac{125}{1000} to lowest terms by extracting and canceling out 125.

$$4+45\times \frac{1}{8}+43\times \frac{1}{8}$$

Multiply 45 and \frac{1}{8} to get \frac{45}{8}.

$$4+\frac{45}{8}+43\times \frac{1}{8}$$

Convert 4 to fraction \frac{32}{8}.

$$\frac{32}{8}+\frac{45}{8}+43\times \frac{1}{8}$$

Since \frac{32}{8} and \frac{45}{8} have the same denominator, add them by adding their numerators.

$$\frac{32+45}{8}+43\times \frac{1}{8}$$

Add 32 and 45 to get 77.

$$\frac{77}{8}+43\times \frac{1}{8}$$

Multiply 43 and \frac{1}{8} to get \frac{43}{8}.

$$\frac{77}{8}+\frac{43}{8}$$

Since \frac{77}{8} and \frac{43}{8} have the same denominator, add them by adding their numerators.

$$\frac{77+43}{8}$$

Add 77 and 43 to get 120.

$$\frac{120}{8}$$

Divide 120 by 8 to get 15.

$$15$$
