\(3-\dfrac{13}{9}=\dfrac{27}{9}-\dfrac{13}{9}=\dfrac{14}{9}\\ \dfrac{194}{64}-2=\dfrac{97}{32}-2=\dfrac{97}{32}-\dfrac{64}{32}=\dfrac{33}{32}\)
\(3-\dfrac{13}{9}=1\dfrac{5}{9}\\ \dfrac{196}{64}-2=1\dfrac{1}{16}\)
\(3-\dfrac{13}{9}=\dfrac{27}{9}-\dfrac{13}{9}=\dfrac{14}{9}\)
\(\dfrac{196}{64}-2=\dfrac{49}{16}-2=\dfrac{49}{16}-\dfrac{32}{16}=\dfrac{17}{16}\)
\(3-\dfrac{13}{9}\)
= \(\dfrac{27}{9}-\dfrac{13}{9}=\dfrac{14}{9}\)
\(\dfrac{196}{64}-2\)
\(=\dfrac{97}{32}-2=\dfrac{97}{32}-\dfrac{64}{32}=\dfrac{33}{32}\)
