Solve 21/2+1/4div2/8

$$2 \frac { 1 } { 2 } + \frac { 1 } { 4 } \div \frac { 2 } { 8 }$$

Evaluate

$$\frac{7}{2}=3.5$$

Solution Steps

Multiply 2 and 2 to get 4.

$$\frac{4+1}{2}+\frac{\frac{1}{4}}{\frac{2}{8}}$$

Add 4 and 1 to get 5.

$$\frac{5}{2}+\frac{\frac{1}{4}}{\frac{2}{8}}$$

Divide \frac{1}{4} by \frac{2}{8} by multiplying \frac{1}{4} by the reciprocal of \frac{2}{8}.

$$\frac{5}{2}+\frac{8}{4\times 2}$$

Multiply 4 and 2 to get 8.

$$\frac{5}{2}+\frac{8}{8}$$

Divide 8 by 8 to get 1.

$$\frac{5}{2}+1$$

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

$$\frac{5}{2}+\frac{2}{2}$$

Since \frac{5}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.

$$\frac{5+2}{2}$$

Add 5 and 2 to get 7.

$$\frac{7}{2}$$

Factor

$$\frac{7}{2} = 3\frac{1}{2} = 3.5$$
