Because if you put them into groups you would get the answer bye using your timetables.
|
60.67%
|
Convert ⅝ into percentage probability.
|
100 divide equals 11 then divide 5 times then you would get the answer..
|
55%
|
Convert 12/18 into percentage probability
|
Because you have to have 12 people or anything to do it so you would have to make sure it goes up to 100 so you would get 18 to get the number then it would be 65.57.
|
65.57

LI: to learn how to make a game.
Today for Maths I made a game and also a video. What did you learned? I learnt how to make a kind of good video and a good planning. I also learnt how to make my planning kind of detail for people to see on my blog. How did you learned? I worked with Nyjah. I had Florence to help me and Nyjah for our Maths which was very nice of her to do. We also had 2 must dos. We had to publish both of them but I had to do my probability first.
