## anonymous 5 years ago Which ratio is NOT equilvalent to 6/16? A. 3/8 B. 15/40 C. 24/54 D. 60/160

C?

2. anonymous

need an explanation plz dont guess.

if you devide (top)/(top) you should get the same answer as (bottom) / (bottom) A:${6\over3} = {16 \over 8} = 2$ B:${6\over15} = {16 \over 40} = {2 \over 5 } = 0.4$ C:${6\over24} \neq {16 \over 54} \rightarrow \rightarrow {1 \over 4} \neq {8 \over 27}$ D:${6 \over 60} = {16 \over 160} = {1\over 10} = 0.1$

7. anonymous

8. anonymous

the ratio has to be the same. plug in the answers in your calculator it will give you .375 for all except C which is .444

take a look at the first one. if you multiply top and bottom of 3/8 by 2 then you get 6/16 which is equivalent

13. anonymous

that means the ratio is the same.
