In these problems, we should remember how to carry out operations with fractions.Carefully read the following problem and the steps we have taken to solve it: We find the common denominator: We calculate: Answer: Finally, we are going to look at an example of a word problem with a fraction and a whole number.Example 1: Rachel rode her bike for one-fifth of a mile on Monday and two-fifths of a mile on Tuesday. Analysis: To solve this problem, we will add two fractions with like denominators.Solution: Answer: Rachel rode her bike for three-fifths of a mile altogether.Now we will have to convert all the information into a fraction with the same denominator (as we did in the example above) in order to calculate We convert 1 into a fraction with the same denominator: We calculate: Answer: What do you think of this post?Do you see how easy it is to solve word problems with fractions? Next, an easy way to divide would be to the reciprocal method.You would leave he first fraction in the problem as 12/1, then you would turn 12/13 into 13/12 and then simply multiply across to get your answer.
