Question

Answer 1

\(=\left(\dfrac{7}{15}-\dfrac{2}{15}\right)+\left(\dfrac{5}{12}+\dfrac{7}{12}\right)=\dfrac{1}{3}+1=\dfrac{4}{3}\)

Answer 2

4/3

Answer 3

=(5/12 + 7/12) + (17/15 - 2/15)

=1 + 1=2

Answer 4

\(=\left(\dfrac{5}{12}+\dfrac{7}{12}\right)+\left(\dfrac{17}{15}-\dfrac{2}{15}\right)\)

\(=1+1\)

\(=2\)

Answer 5

=(7/15−2/15)+(5/12+7/12)=1/3+1=4/3

Answer 6

=(7/15−2/15)+(5/12+7/12)=1/3+1=4/3
