@amistre64

amistre64 · Answer

a proportion is defined as equal ratios
you can chk by "cross multiplying"

amistre64 · Answer

$$if~\frac ab=\frac cd,~then~ad=bc$$

amistre64 · Answer

since 3(18) not= 8(6) ... that is not the correct option

amistre64 · Answer

but you have a typo ....

three over eight equals six over sixteen
  3       /     8        =      6   /     16

3(16) = 8(6)
  48   =  48

anonymous · Answer

when you do cross multiplying would you multiply by ad then bc?

amistre64 · Answer

ad and bc  are the RESULT of cross multiplying .....
