Answer:
Step-by-step explanation:
First convert the mixed fractions to improper fraction.
Then find the Least common denominator. Here LCD = 100
Then find equivalent fractions and subtract
[tex]32\dfrac{3}{10}-12\dfrac{1}{100} = \dfrac{323}{10}-\dfrac{1201}{100}\\\\\\
=\dfrac{323*10}{10*10}-\dfrac{1201}{100}\\\\\\
=\dfrac{3230}{100}-\dfrac{1201}{100}\\\\\\
=\dfrac{3230-1201}{100}\\\\
=\dfrac{2029}{100}\\\\
=20\dfrac{29}{100}[/tex]
