Maths prove it

WALT calculate percentages of amounts

Here is some examples of what we have been working on

20% of $32 the awnser is $6.40

I worked it out by putting 20 then the 32  now you times 100 times 1           then you times 20 by 32

                                       100             1                                                100

which would look like this 640 now all you need to do is put $ infrount of the 6 $6.40 and the dot were 

                                        100

it is then you have the awsner.
