Capitolo 1, Problema 87
Simplify each complex fraction. See Examples 5 and 6. (1/(x + 1) − 1/x) / (1/x)
Guida verificata passo dopo passo1
Rewrite the complex fraction clearly to understand its structure. The expression is: \(\frac{\frac{1}{x+1} - \frac{1}{x}}{\frac{1}{x}}\).
Focus on simplifying the numerator first: \(\frac{1}{x+1} - \frac{1}{x}\). Find a common denominator for these two fractions, which is \(x(x+1)\).
Rewrite each fraction in the numerator with the common denominator: \(\frac{x}{x(x+1)} - \frac{x+1}{x(x+1)}\).
Combine the fractions in the numerator by subtracting the numerators over the common denominator: \(\frac{x - (x+1)}{x(x+1)}\).
Simplify the numerator of the combined fraction and then divide this result by the denominator \(\frac{1}{x}\) by multiplying by its reciprocal.

Complex Fractions
A complex fraction is a fraction where the numerator, denominator, or both contain fractions themselves. Simplifying involves rewriting the expression as a single fraction by finding common denominators or multiplying numerator and denominator by the least common denominator to eliminate smaller fractions.
