Q. Subtract.\newline110−910=\frac{1}{10} - \frac{9}{10} = _____
  1. Convert to Fraction: 110−910\frac{1}{10} - \frac{9}{10}\newlineWrite it as a fraction with a common denominator.\newline110−910\frac{1}{10} - \frac{9}{10} \newline=(1−9)10= \frac{(1-9)}{10}\newline=−810= \frac{-8}{10}
  2. Simplify Fraction: Simplify −810-\frac{8}{10}. We can reduce the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 22. −810=(−82)/(102)=−45-\frac{8}{10} = \left(-\frac{8}{2}\right) / \left(\frac{10}{2}\right) = -\frac{4}{5}
