PART ONE:
To put this information into a fraction you write part over whole:
[tex]8/40[/tex]
To change this into a decimal you have to plug in 8÷40 into your calculator:
0.2
PART TWO:
After you subtract 8 from 40, there are 32 fifth graders left.
The fraction will look like this:
[tex]32/40[/tex]
To change this into a decimal you have to plug in 32÷40 into your calculator:
0.8
