The way to solve this is to simplify the ratios. 55 and 100 can both be divided by 5 to get 11:20. 66 and 120 can both be divided by 6 to get 11:20. Since the traps simplify to the same thing, yes, they are equivalent.
Yes they are because if you simplify them both then they both equal 11:20 so they are equivalent ratios
The ratios 55:100 and 66:120 simplify to 11:20, indicating they are equivalent. Therefore, 55:100 is equal to 66:120. They both share the same simplest form.
