Question

Which of the following fractions is not equivalent to 2/ 7 a = 4/14b = 4/21c = 6/21d = 8/28

Answer 1

to find the fraction that's not equivalent to 2/7, we know to know the quotient of each fraction and compare to find the odd one out

`(2)/(7)=0.285`

now let's check for each options

a =

`(4)/(17)=(2)/(7)=0.285`

b =

`(4)/(21)=0.190`

c =

`(6)/(21)=(2)/(7)=0.285`

d =

`(8)/(28)=(2)/(7)=0.285`

from the options given, the fraction that's not equivalent to 2/7 is 4/21 which is options B
