Question

3-1/5

12-40/13       

Answer 1

3/1- 1/5= 15/5-1/5= 14/5

12/1-40/13= 156/13- 40/13= 116/13

Answer 2

\(3-\dfrac{1}{5}=\dfrac{15}{5}-\dfrac{1}{5}=\dfrac{14}{5}\\ 12-\dfrac{40}{13}=\dfrac{156}{13}-\dfrac{40}{13}=\dfrac{116}{13}\)

Answer 3

3-1/5=\(\dfrac{15}{5}-\dfrac{1}{5}=\dfrac{14}{5}\)

12-40/13=\(\dfrac{156}{13}-\dfrac{40}{13}=\dfrac{116}{13}\)

Answer 4

= 14/5

= 32/3

Answer 5

116/13

Answer 6

3/1-1/5=15/5-1/5=14/5

12/1-40/13=156/3-40/13=116/13
