Question

Answer 1

5/9+ 2/3

= 5/9+ 6/9

= 11/9

13/15- 4/5

= 13/15- 12/15

= 1/15

5/12x4/3-1/3

= 5/9- 1/3

= 5/9- 3/9

= 2/9

(5/1-3/5) x 5/8

= (25/5- 3/5)x 5/8

= 22/5 x 5/8

= 110/40

= 11/4

Answer 2

\(\dfrac{5}{9}+\dfrac{2}{3}=\dfrac{5}{9}+\dfrac{6}{9}=\dfrac{11}{9}\)

\(\dfrac{13}{15}-\dfrac{4}{5}=\dfrac{13}{15}-\dfrac{12}{15}=\dfrac{1}{15}\)

\(\dfrac{5}{12}x\dfrac{4}{3}-\dfrac{1}{3}=\dfrac{20}{36}-\dfrac{1}{3}=\dfrac{8}{36}\)

\(\left(5-\dfrac{3}{5}\right)x\dfrac{5}{8}=\dfrac{22}{5}x\dfrac{5}{8}=\dfrac{22}{8}\)
