$$770$$

Solution Steps

Multiply \frac{22}{7} times \frac{7}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{22\times 7}{7\times 2}\times \frac{7}{2}\times \frac{20}{1}$$

Cancel out 7 in both numerator and denominator.

$$\frac{22}{2}\times \frac{7}{2}\times \frac{20}{1}$$

Divide 22 by 2 to get 11.

$$11\times \frac{7}{2}\times \frac{20}{1}$$

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

$$\frac{11\times 7}{2}\times \frac{20}{1}$$

Multiply 11 and 7 to get 77.

$$\frac{77}{2}\times \frac{20}{1}$$

Anything divided by one gives itself.

$$\frac{77}{2}\times 20$$

Express \frac{77}{2}\times 20 as a single fraction.

$$\frac{77\times 20}{2}$$

Multiply 77 and 20 to get 1540.

$$\frac{1540}{2}$$

Divide 1540 by 2 to get 770.

$$770$$

Factor

$$2\times 5\times 7\times 11$$
