Answer 1

\(\left(\dfrac{3}{29}-\dfrac{1}{5}\right).\dfrac{29}{3}=\dfrac{3}{29}.\dfrac{29}{3}-\dfrac{1}{5}.\dfrac{29}{3}=1-\dfrac{29}{15}=\dfrac{-14}{15}.\)

Answer 2

(3/29-1/5)*29/3

=(15/145-29/145)*29/3

=(15/145+-29/145)*29/3

=-14/145*29/3

=-14/15

Answer 3

\(\dfrac{14}{15}\)

Answer 4

(3/29-1/5)*29/3
