My Maths Strategy Week 5

12. Tama is making costumes for the production. Each of the costumes he makes uses  .39m2 of material. How many can he make with 33m2

I needed to know what the answer to this question was. The first thing I done was times .39x10 which equals 3.9. I then doubled that which would equal 7.8 and that will make 20. Again I doubled it which made 15.6 (40 costumes). Doubled it again and I made 31.2 (80 costumes) That meant there was 1.8 left. Out of that I could make 4 with .24 left over. So that makes 84 costumes.
