Which expressions have some greater than 20 select all that apply

15.16+4.09
0.8+19.3
13.36+6
8.3+11.8
10.09+9.9

1 answer

Let's evaluate each expression to see if the sum is greater than 20:

  1. 15.16 + 4.09
    \( 15.16 + 4.09 = 19.25 \) (not greater than 20)

  2. 0.8 + 19.3
    \( 0.8 + 19.3 = 20.1 \) (greater than 20)

  3. 13.36 + 6
    \( 13.36 + 6 = 19.36 \) (not greater than 20)

  4. 8.3 + 11.8
    \( 8.3 + 11.8 = 20.1 \) (greater than 20)

  5. 10.09 + 9.9
    \( 10.09 + 9.9 = 19.99 \) (not greater than 20)

Based on these calculations, the expressions that result in sums greater than 20 are:

  • 0.8 + 19.3
  • 8.3 + 11.8
