a)

 

I don't know what kind of diagram it wants.....but we can calculate the percenteges like this:

 

We can replace the  %  sign with  / 100

And we can replace the word "of" with *

So.....

 

i)

 

ii)

 

iii)

 

iv)

__

400%  of  240   =   400/100  *  240   =   4 * 240   =   960

 

40%  of  240   =   40/100  *  240   =   4/10  *   240   =   ?

 

4%  of  240   =   4/100  *  240   =   ?

 

0.4%  of  240   =   0.4/100 * 240   =   ?

 

 

Can you finish those?

 

After you get the answers for these, you might notice the pattern that they are talking about in part b. smiley
