1 answer

Let's calculate the sums of each expression:

  1. 15.16 + 4.09 = 19.25 (not greater than 20)
  2. 0.8 + 19.3 = 20.1 (greater than 20)
  3. 13.36 + 6 = 19.36 (not greater than 20)
  4. 8.3 + 11.8 = 20.1 (greater than 20)
  5. 10.09 + 9.9 = 19.99 (not greater than 20)

The following expressions have a sum greater than 20:

  • 0.8 + 19.3
  • 8.3 + 11.8
