What is 4.50+3.4+12.09 ?​

Answer 1

The answer to this equation is 19.99. If you round the number, it is 20.

Step-by-step explanation:

4.50

3.40 (0 as a place holder)

+ 12.09

19.99 because . . .

4.5 + 3.4 = 7.9

7.9 + 12.09 = 19.99.

19.99 ≅ 20.00 or 20 (IF YOU NEED TO ROUND IT, IF NOT, IT IS JUST 19.99!!!)

Answer 2

19.99

Step-by-step explanation:

The steps are what I did, so no need to do it the exact same!

1. Add 4.50 and 3.4

4.50 + 3.4 = 7.9

7.9 + 12.09 = 19.99
