W.A.L.T: use fractions.
This week we have been giving a fractions problem solving. Why don't you take a look at Week 9 problem which is right here.
This week I have learnt that 4/7 is is bigger than 3/8 . Because Zack needs 3 more and B.J needs 5 more. Now that I now how to do it I can give you an example if I have 7/9 and Seini has 7/8 I know that it would be Seini because she only needs one more to complete her to do list and I need to more to complete my to do list.
