Question

Answer 1

\(=\dfrac{14}{35}+\dfrac{15}{35}+\dfrac{8}{35}=\dfrac{37}{35}\)

Answer 2

\(\dfrac{2}{5}\) + \(\dfrac{3}{7}\)+ \(\dfrac{8}{35}\)= \(\dfrac{37}{35}\)

Answer 3

\(\dfrac{14}{35}+\dfrac{15}{35}-\dfrac{8}{35}=\dfrac{29}{35}-\dfrac{8}{35}=\dfrac{21}{35}\)

Answer 4

\(\dfrac 2 5+\dfrac 3 7-\dfrac 8 {35}\)

=\(\dfrac {14} {35} + \dfrac {15} {35} - \dfrac 8 {35}\)

=\(\dfrac {21} {35}\)
