Q. Subtract.\newline910−110=\frac{9}{10} - \frac{1}{10} = _____
  1. Write Subtraction Problem: Write the subtraction problem with a common denominator.\newline910−110\frac{9}{10} - \frac{1}{10}\newlineBoth fractions have the same denominator, so we can subtract the numerators directly.
  2. Subtract Numerators: Subtract the numerators and write the result over the common denominator.\newline910−110=(9−1)10\frac{9}{10} - \frac{1}{10} = \frac{(9-1)}{10}\newline= 810\frac{8}{10}
  3. Simplify Fraction: Simplify the fraction if possible. 8/108/10 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 22. 8/10=(8÷2)/(10÷2)=4/58/10 = (8\div2)/(10\div2) = 4/5
