Question

Which number is not proportional to the others? O 2/4 0 1/2 O 6/12 o 1/3

Answer 1

the numbers are:

$\frac{2}{4},\frac{1}{2},\frac{6}{12},\frac{1}{3}$

so to be proportianal we cave to multiply the number for one number so the become equal so:

$\frac{1}{2}\cdot\frac{2}{2}=\frac{2}{4}$

and

$\frac{1}{2}\cdot\frac{6}{6}=\frac{6}{12}$

so the answer is D 1/3 is not proportional to the others
