Let's calculate the sums of each expression to determine which ones are greater than 20:

  1. \( 15.16 + 4.09 = 19.25 \)
  2. \( 0.8 + 19.3 = 20.1 \)
  3. \( 13.36 + 6 = 19.36 \)
  4. \( 8.3 + 11.8 = 20.1 \)
  5. \( 10.09 + 9.9 = 19.99 \)

Now, let's see which of these sums are greater than 20:

  • \( 15.16 + 4.09 = 19.25 \) (not greater than 20)
  • \( 0.8 + 19.3 = 20.1 \) (greater than 20)
  • \( 13.36 + 6 = 19.36 \) (not greater than 20)
  • \( 8.3 + 11.8 = 20.1 \) (greater than 20)
  • \( 10.09 + 9.9 = 19.99 \) (not greater than 20)

The expressions with a sum greater than 20 are:

  • \( 0.8 + 19.3 \)
  • \( 8.3 + 11.8 \)
