(x)/(5)-(x)/(4) - subtract fractions

Solution for the given fractions

• x/5 - x/4 = ?
• The common denominator of the two fractions is: 20
• x/5 = (4*x)/(4*5) = (4*x)/20
• x/4 = (5*x)/(4*5) = (5*x)/20
• Fractions adjusted to a common denominator
• x/5 - x/4 = (4*x)/20 - (5*x)/20
• (4*x)/20 - (5*x)/20 = (4*x-(5*x))/20
• (4*x-(5*x))/20 = -x/20

Solution for the given fractions

$ \frac{x}{5 }-\frac{ x}{4 }=? $

The common denominator of the two fractions is: 20

$ \frac{x}{5 }= \frac{(4*x)}{(4*5)} = \frac{(4*x)}{20} $

$ \frac{x}{4 }= \frac{(5*x)}{(4*5)} = \frac{(5*x)}{20} $

Fractions adjusted to a common denominator

$ \frac{x}{5 }-\frac{ x}{4 }= \frac{(4*x)}{20 }- \frac{(5*x)}{20} $

$ \frac{(4*x)}{20 }- \frac{(5*x)}{20 }= \frac{(4*x-(5*x))}{20} $

$ \frac{(4*x-(5*x))}{20 }= -\frac{x}{20} $
