Exercise 32 Page 113

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 these fractions in their simplest form. Let's see if the given rates are equivalent! c|c First Ratio & Second Ratio [0.8em] 85 : 210 & 340:735 First, let's write both of them as fractions. c|c First Ratio & Second Ratio [0.8em] 85/210 & 340/735 We need to simplify the above expressions. Let's start by simplifying the first ratio.

Let's now simplify the second rate.

Finally, we can compare the simplified rates. 17/42 ≠ 68/147 Since the fractions are not equivalent, the ratios are not equivalent.
