Exercise 2 Page 119

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] 12/18 & 2/3We need to simplify the above expressions. Since the greatest common factor (GCF) of the numerator and denominator of the second ratio is 1, the fraction is already written in its simplest form. Let's now simplify the rate for the first rate.

12/18

a/b=.a / 2./.b / 2.

22÷ 2/8÷ 2

Simplify quotient

2/3

Finally, we can compare the simplified rates. 2/3 = 2/3 Since the fractions are equivalent, the ratios are equivalent.
