Solve 1div2*22div7*7div2*7div2=

$$1 \div 2 \times 22 \div 7 \times 7 \div 2 \times 7 \div 2=$$

Evaluate

$$\frac{77}{4}=19.25$$

Solution Steps

Multiply \frac{1}{2} and 22 to get \frac{22}{2}.

$$\frac{\frac{\frac{\frac{22}{2}}{7}\times 7}{2}\times 7}{2}$$

Divide 22 by 2 to get 11.

$$\frac{\frac{\frac{11}{7}\times 7}{2}\times 7}{2}$$

Cancel out 7 and 7.

$$\frac{\frac{11}{2}\times 7}{2}$$

Express \frac{11}{2}\times 7 as a single fraction.

$$\frac{\frac{11\times 7}{2}}{2}$$

Multiply 11 and 7 to get 77.

$$\frac{\frac{77}{2}}{2}$$

Express \frac{\frac{77}{2}}{2} as a single fraction.

$$\frac{77}{2\times 2}$$

Multiply 2 and 2 to get 4.

$$\frac{77}{4}$$

Factor

$$\frac{7 \cdot 11}{2 ^ {2}} = 19\frac{1}{4} = 19.25$$
