Samuel said that 16:36 was equivalent to 72:32. What was Samuel's error? The ratio was not chosen from the same columns. He did not look at the correct rows. This problem was impossible. 16:36 has no equivalent ratios. The first and second terms for both ratios need to be in the same order.

Answer:The first and second terms for both ratios need to be in the same order.Step-by-step explanation:Given ratio is 16:36The equivalent ratio that is given: 72:32In order to find any ratio equivalent to given ratio, the ratio can be divided by a number or multiplied to a number.If we multiply the given ratio 16:32 by 2 we get;[tex]\frac{16\times 2}{32\times2}= \frac{32}{72}[/tex]So,we can see that Samuel has interchange the ratio while performing calculation. Looking at the options we can conclude that the right answer isThe first and second terms for both ratios need to be in the same order.
