Solution Steps

Express \frac{\frac{\frac{\frac{90\times 89\times 88\times 87\times 86}{5}}{4}}{3}}{2} as a single fraction.

$$\frac{\frac{\frac{90\times 89\times 88\times 87\times 86}{5}}{4}}{3\times 2}$$

Express \frac{\frac{90\times 89\times 88\times 87\times 86}{5}}{4} as a single fraction.

$$\frac{\frac{90\times 89\times 88\times 87\times 86}{5\times 4}}{3\times 2}$$

Cancel out 2\times 2\times 5 in both numerator and denominator.

$$\frac{9\times 44\times 86\times 87\times 89}{3\times 2}$$
