Which ratio is equivalent to 4 : 13?


A.


8 : 17


B.
16 : 52


C.
12 : 33


D.
20 : 55

Answer 1

4:13 is the same as 4/13

let's test choice A

8:17 is the same as 8/17

-------------------------------------------------------

so IF 4:13 is equivalent to 8:17, then this equation must be true

4/13 = 8/17

Answer 2

ok

Answer 3

you can cross multiply to check

4/13 = 8/17

4*17 = 13*8

68 = 104


The fact that 68 = 104 is false means that 4/13 = 8/17 is false

Answer 4

so 4:13 is NOT equivalent to 8:17

Answer 5

you'll check the other choices that way
