Ordering and Comparing Fractions

In Maths today we have been learning to compare and order fractions by converting them to have the same Denominator. This then allowed us to see which one would be bigger.

Rowan wrote a very tricky problem for us to have a go at, can you solve it and leave your answer as a comment?

Bob cut a cake into 12 slices.
He then took 5 pieces.

Rhianna took the remaining pieces and cut them into the smallest even number possible.
The then took 9 pieces.

Who ate the most cake?

​Good luck!
