Answer 2

Let's solve this step by step:

1. 450 divided by 5 equals 90.
2. 720 divided by 90 equals 8.

Now, let's solve the first part:

450:5 + 720:90 = 90 + 8 = 98

Next, let's work on the second part:

1. 810 divided by 9 equals 90.
2. 580 minus 90 equals 490.
3. Finally, add 210 to 490.

So, 580 - 810:9 + 210 = 490 + 210 = 700.

Therefore, the final answer is:

450:5 + 720:90 = 98 580 - 810:9 + 210 = 700
