5/9 - 3/12

Answer 1

\(\dfrac{5}{9}-\dfrac{3}{12}=\dfrac{5}{9}-\dfrac{1}{4}=\dfrac{20}{36}-\dfrac{9}{36}=\dfrac{20-9}{36}=\dfrac{11}{36}\)

Answer 2

\(\dfrac{5}{9}-\dfrac{3}{12}=\dfrac{5}{9}-\dfrac{1}{3}=\dfrac{5}{9}-\dfrac{3}{9}=\dfrac{2}{9}\)

Answer 3

= \(\dfrac{5}{9}\) - \(\dfrac{1}{4}\)

= \(\dfrac{11}{36}\)

Answer 4

\(\dfrac{5}{9}\)-\(\dfrac{3}{12}\)

=\(\dfrac{60}{108}\)-\(\dfrac{27}{108}\)

=\(\dfrac{33}{108}\)=\(\dfrac{11}{36}\)
