Question

All of the following are equivalent to 8/10 except

A.5/6
B.4/5
c.16/20
D.40/50

Answer 1

The values of the expressions B, C and D are all 0.8. The value of expression A is 5/6, or 0.83333... , so this is the exception to the rule (value = 0.8).

Answer 2

A. 5/6 is your answer

Proof:

(8/10)/(2/2) = 4/5

(8/10)(2/2) = 16/20

(8/10)(5/5) = 40/50

hope this helps
