Find the odd number / letters / word from the given alternative:

0.825
1.054166667
0.888888889
26 : 156

The answer is C. 20 : 80.

In each of the other options, the second number is the product of the first number and 7.

  • 18 x 7 = 126
  • 23 x 7 = 161
  • 26 x 7 = 182

However, 20 x 7 = 140, not 80.
