Both fractions and decimals are just ways to represent numbers. They should also recognise mixed numbers and improper fractions and convert from one form to the other and write mathematical statements > 1 as a mixed number [for example, 2/5 + 4/5 = 6/5 = 1 and 1/5]. A non-unit fraction is a proper or improper fraction where the numerator is greater than 1 and the denominator is a whole number. Because it is a ratio, mole fraction is a unitless expression. No matter how a ratio is written, it is important that it be simplified down to the smallest whole numbers possible, just as with any fraction. Solution.
