$$\frac { 11 C _ { 2 } } { 5 C _ { 2 } }$$

Evaluate

$$\frac{11}{5}=2.2$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{11^{1}C_{2}^{1}}{5^{1}C_{2}^{1}}$$

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{11^{1}C_{2}^{1-1}}{5^{1}}$$

Subtract 1 from 1.

$$\frac{11^{1}C_{2}^{0}}{5^{1}}$$

For any number a except 0, a^{0}=1.

$$\frac{11^{1}}{5^{1}}$$

Divide 11 by 5.

$$\frac{11}{5}$$

Factor

$$\frac{11}{5} = 2\frac{1}{5} = 2.2$$
