As you can see, this equation is not valid – 8 is the product of 2 times 4 and 9 is the product of 3 times 3. That means that these ratios are not proportional. If we wanted to find the proportional ratio to 2/3 while keeping the denominator of the other ratio, we would have to multiply the numerator 2 with the number 3. I could multiply 25 by 3 to get 75. Success for English Learners 1. 12.6 2. 75% is 75 hundredths or 75 100 3. You can find the percent of a number by using a proportion as in Problem 1 or by changing the percent to a decimal and multiplying as in Problem 2.
