All choices agree that it is "six and (something)".

So, you're asked to figure out whether 0.2 + 0.07 = 0.27 is

  • twenty-seven
  • twenty-seven tenths
  • twenty-seven hundredths
  • twenty-seven thousandths

You can start with the original expanded form to decide

... (2 × 0.1) + (7 × 0.01) = (20 × 0.01) + (7 × 0.01)

... = (20+7) × 0.01 = (27 × 0.01)

Since you know 0.01 is 1 hundredth, you know the correct choice is ...

... six and twenty-seven hundredths

the answer would be -six and twenty-seven hundredths
