To find equal ratios by first write the given ratio as a fraction, then multiply the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7.
4 , 8 , 12 , 16 are all equal ratios. Divide each term by the same nonzero number will give an equal ratio. Remember: when you divide you must select a number by which both terms are divisible. So, 1 : 2, 3 : 6, and 6 : 12 are all equal ratios.
The ratio 2 : 3 is the same as the ratio of 6 : 15. 2.) This is an example of scaling down by a scale factor of 5. The ratio 8 to 11 is the same as the ratio 40 : 55.
