This week in maths we where working on decimals and fractions.
one of the questions was if 3/5 of the school is boys, and 2/5 girls. There is 2000 students. how many are girls?
The way I worked this out was I found out what 2/5 of 1000 is which is 400. then I doubled it.
giving me 800 which was the right answer.
Something else we are doing in maths is decimals into fractions into percentages.
like this
0.86 = 86/100 = 86%
And the hardest thing for me was one of the questions on a sheet we did.
here is the question
here is a graph. the students at a school were asked to vote for there favourite lunch item.
Pies- 25%
chocolate 38%
Chips 27%
etc
there is 5000 kids at the school. how many preferred chocolate.
I worked this question out by first figuring out the 38% of 100 which is 38.
then I times 38 by 5
38 x 38 x 38 x 38 x 38 = 190.
190 is the answer
so 190 is the answer.

Just a quick question. Did you mean to write that there were 500 kids at the school? Or are there really 5000? Because if there are 5000 your answer needs one more zero. Aside from that, good figuring...
