need an explanation plz dont guess.

anonymous · Answer

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:$${6 \over 60} = {16 \over 160} = {1\over 10} = 0.1$$

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

m · Answer

that means the ratio is the same.
