Question

Write as a fraction or mixed number in simplest form. 0.548

Answer 1

Fraction . . . 548/1000 = 137/250

Mixed number . . .
A mixed number is a whole number plus a fraction.  The smallest
whole number is '1 ', so a mixed number is always more than ' 1 '. 
But 0.548 is less than ' 1', so there's nothing you can do with it
to make a mixed number.
