Exercise 2 Page 156

One way to know if two ratios or rates are equivalent is by writing them as fractions. We can check if the relationship between the two quantities is the same when we compare their fraction form in their simplest form. Let's see if the given ratios are equivalent! c|c First Ratio & Second Ratio [0.8em] 8:7 → 8/7 & 15:14 → 15/14 We need to simplify the above expressions. Since the greatest common factor (GCF) of the numerator and denominator of both rates is 1, the fractions are already written in its simplest form. Let's compare the simplified rates. 8/7 ≠ 15/14 Since the fractions are not equivalent, the ratios are not equivalent.
