Question

7/15+18/15          5/4+17/12          1/2+1/6+2/3           2+1/3

Answer 1

\(\dfrac{7}{15}+\dfrac{8}{15}=1\)

\(\dfrac{5}{4}+\dfrac{17}{12}=\dfrac{15}{12}+\dfrac{17}{12}=\dfrac{32}{12}=\dfrac{8}{3}\)

\(\dfrac{1}{2}+\dfrac{1}{6}+\dfrac{2}{3}=\dfrac{3}{6}+\dfrac{1}{6}+\dfrac{4}{6}=\dfrac{8}{6}=\dfrac{4}{3}\)

\(2+\dfrac{1}{3}=\dfrac{6}{3}+\dfrac{1}{3}=\dfrac{7}{3}\)

Answer 2

7/15+18/15 = 25/15 = 5/3          5/4+17/12= 15/12 + 17/12 = 32/12 = 8/3          1/2+1/6+2/3 = 3/6 + 1/6 + 4/6 = 8/6 = 4/3          2+1/3 = 7/3

Answer 3

8/3
4/3
7/3

Answer 5

7/15+18/15 = 25/15 = 5/3         
5/4+17/12= 15/12 + 17/12 = 32/12 = 8/3         
1/2+1/6+2/3 = 3/6 + 1/6 + 4/6 = 8/6 = 4/3         
2+1/3 = 7/3
