Maths

Today our group (Tahi) had a maths session, We were split into 4 groups and my group and I work on a problem that our teacher gave to us. The was our teacher (Mrs Tofa) is cooking Pineapple Pies, Coconut cream buns and Coconut bread, we need 2/3 of a bag flour for the Pineapple pies, 5/6 of a bag of flour for the Coconut Cream and 5/12 of a bag of flour for the Coconut bread. My group and I were very confused in the first place and then when we got some help from our teacher Miss Woodhall we finally understand something, our strategie was:

2 x 4 = 8

3 x 4 = 12

5 x 2 = 10

6 x 2 = 12

And we didn't need to anything to 5/12

We added 8 + 10 + 5 = 23

So it was 23/12 but that can not be possible, but there one 12 in 23 so that one whole and theres one 12 in 23 but we had 11 left and we got 1 whole and 11/12
