Question 168817
{{{9/24}}} and {{{15/40}}} ---> proportion?
>>>Statement of equality, okay.
{{{(9/24)=(15/40)}}}, cross multiply
{{{9*40=15*24}}}
{{{360=360}}}, Proportion
Another way,
{{{(9/24)}}}, divide both num & den by 3
{{{(3/8)}}} ----> A
And, {{{15/24}}}, divide both num & den by 5
{{{3/8}}}-----> B
As you see, {{{A=B}}}, proportion.
Thank you,
