Question

so on one of my 6th grade practice test for the big test tomorrow and it said " which of the ratios below are equivalent to 10:12 circle all that may apply" and i was wondering how i find the equivalents

Answer 1

well, the lowest is 5 : 6 , using whole numbers.
That one should appear.
Any others should be multiples of that, e.g. 25 : 30

Answer 2

10:12 = 2*5 : 2*6 = 5:6
so, any ratio where 5/6 is multiplied by the same amount both on top and on bottom, will be equivalent
