Answer 3

 \(\dfrac{55}{110}=\dfrac{55:55}{110:55}=\dfrac{1}{2}\)

 \(\dfrac{72}{96}=\dfrac{72:24}{96:24}=\dfrac{3}{4}\)

\(\dfrac{88}{99}=\dfrac{88:11}{99:11}=\dfrac{8}{9}\)

Answer 4

\(\dfrac{55}{110}\)= \(\dfrac{55:55}{110:55}\)= \(\dfrac{1}{2}\)

\(\dfrac{72}{96}\) = \(\dfrac{72:24}{96:24}\)= \(\dfrac{3}{4}\)

\(\dfrac{88}{99}\) = \(\dfrac{88:11}{99:11}\)= \(\dfrac{8}{9}\)
