a whole number
A whole stick is worth 1 whole, use fraction sticks to find equivalent fractions, use the fraction sticks to add fractions with the same denominator
no. lets use 10,000,000,000,000, which is a whole number, and 1 1/2, which is a mixed number. all a mixed number is is a mix of fractions and whole numbers,
The answer depends on "instead of WHAT?"Rational fractions, percentages and decimal fractions are fractions: they are simply different ways of representing parts of a whole. So the choice cannot be between these. If the choice is between fractions and whole numbers, the answer is depends on the degree of accuracy required and the units in use. For example, if measuring your height, a whole number of centimetres would be appropriate but for metres, you would want fractional values (to hundredths of a metre).
To get an equivalent fraction, multiply top and bottom by the same number. Any number except zero will do; but to avoid compound fractions, you'll probably want to use whole numbers.
