Answer 1

\(=\dfrac{30}{36}+\left(\dfrac{20}{36}-\dfrac{9}{36}\right)=\dfrac{30}{36}+\dfrac{11}{36}=\dfrac{41}{36}\)

Answer 2

=5/6+11/36

=41/36

Answer 3

\(=\dfrac{30}{36}+\dfrac{20}{36}-\dfrac{45}{36}=\dfrac{5}{36}\)

Answer 4

\(\dfrac{5}{6}+\left(\dfrac{5}{9}-\dfrac{5}{4}\right)=\dfrac{5}{6}+\left(\dfrac{20}{36}-\dfrac{45}{36}\right)=\dfrac{5}{6}-\dfrac{25}{36}=\dfrac{30}{36}-\dfrac{25}{36}=\dfrac{5}{36}\)

Answer 5

Answer 6

5/6 + ( 5/9 - 1/4)

= 5/6 +   11/36

=      41/36

Answer 7

\(\dfrac{5}{6}+\left(\dfrac{5}{9}-\dfrac{1}{4}\right)\)

\(\dfrac{5.6}{6.6}+\left(\dfrac{5.4}{9.4}-\dfrac{1.9}{4.9}\right)\)

\(\dfrac{30}{36}+\left(\dfrac{20}{36}-\dfrac{9}{36}\right)\)

\(\dfrac{30}{36}+\dfrac{11}{36}\)

=\(\dfrac{41}{36}\)
