Answer 1

a: 13/35=1/5+1/7+1/35

b: =\(\dfrac{8}{27}+\dfrac{19}{27}+\dfrac{4}{15}+\dfrac{11}{15}=1+1=2\)

Answer 2

a) \(\dfrac{1}{35}+\dfrac{1}{7}+\dfrac{1}{5}\)

b) \(\)\(\left(\dfrac{8}{27}+\dfrac{19}{27}\right)+\left(\dfrac{4}{15}+\dfrac{11}{15}\right)=1+1=2\)

Answer 3

a)`13/35 = 1/7 + 1/5 + 1/35`

b) `8/27 = 5/15 + 19/27 + 11/15`

= ` (8/27 + 19/27)+(4/15 +11/15)`

= `1 + 1` 

= `2`
