Write Subtraction Problem: Write the subtraction problem with a common denominator. $\newline$ $\frac{9}{10} - \frac{4}{5}$ $\newline$ To find a common denominator, we can convert $\frac{4}{5}$ to have a denominator of $10$ , which is the least common multiple of $5$ and $10$ . $\newline$ $\frac{4}{5} = \left(\frac{4\times2}{5\times2}\right) = \frac{8}{10}$ $\newline$ Now we can rewrite the subtraction problem as: $\newline$ $\frac{9}{10} - \frac{8}{10}$
Find Common Denominator: Subtract the numerators and keep the common denominator. $\newline$ $\frac{9}{10} - \frac{8}{10} = \frac{(9-8)}{10}$ $\newline$ $9-8 = 1$ $\newline$ So the subtraction gives us: $\newline$ $\frac{1}{10}$
