Adding and subtracting mixed numbers
In this section, we will write addition and subtraction statements for mixed numbers using given diagrams. First, we will add and subtract the whole numbers. Second, we will add and subtract the fractions. Some of the fractions will have like denominators and others will have unlike denominators. Before adding and subtracting those fractions with unlike denominators, we will have to determine the lowest common denominator for the pair of fractions and then write the equivalent fractions. We will write any resulting improper fractions in our answers as mixed numbers.
