A mixed number is (a whole number) plus (a fraction).
The whole number is no problem. It's ' 2 ' .
But how to get a fraction from .98 ?
The easiest way I know to explain it is: Read it out loud, and
write down what you hear yourself saying.
When you read ' .98 ' out loud, you should say
"ninety-eight hundredths" .
Write that down: 98/100 . There's your fraction.
It looks a little bit neater if you simplify it ... divide
the top and bottom by 2 , and then you have 49/50 .
So 2.98 is the same as the mixed number ( 2 and 49/50 ).
