Question

Answer 1

\(\dfrac{65+29}{47}+\dfrac{20+37}{57}=\dfrac{94}{47}+\dfrac{57}{57}=2+1=3\)

Answer 2

\((65/47+29/47)+(20/57+37/57)=2+1=3\)

Answer 3

\(=\left(\dfrac{65}{47}+\dfrac{29}{47}\right)+\left(\dfrac{20}{57}+\dfrac{37}{57}\right)\\ =2+1=3\)

Answer 4

Answer 5

\(\dfrac{65}{47}+\dfrac{20}{57}+\dfrac{37}{57}+\dfrac{29}{47}\)

\(=\left(\dfrac{65}{47}+\dfrac{29}{47}\right)+\left(\dfrac{20}{57}+\dfrac{37}{57}\right)\)

\(=2+1\)

\(=3\)
