Question

Tell wether the ratios are equivalent or not equivalent 16:3,27:5

Answer 1

ratios are nothing but fractions
16:3 is the same as 16/3
27:5 is the same as 27/5

to see if they are equivalent, lets make a proportion
16/3 = 27/5 --- cross multiply
(27)(3) = (16)(5)
81 = 80 (incorrect) --- these are not equivalent
