Which of the following is not a proportion ⁴/5 = 8/10 18/6 = 12/4 6/16 = 3/8 27/9= 22/4

OpenStudy (anonymous):

Please help me

OpenStudy (cwrw238):

one way to find out would to be to reduce to the simplest form for example 8/10 = 4/5 - you get this by dividing top and bottom by 2 so the first is in proportion

OpenStudy (anonymous):

Thank you :-)

OpenStudy (cwrw238):

with the second one try dividing 18/16 ( top and bottom) by 3 and divide top bottom of 12/4 by 4 what do you get?

OpenStudy (cwrw238):

* sorry first one should be 18/6 divide top/bottom by 6

OpenStudy (cwrw238):

do you see what i mean@ i'm simplifying them by dividing by the Greatest common factor of the two numbers
