Answer 2

It seems like you are providing some mathematical equations and their solutions. Let's take a look at each of them to see if they are correct:

1. 70 • 4 = 280 (not 28)
2. 8 • 30 = 240 (correct)
3. 25 • 4 = 100 (correct)
4. 68 • 5 = 340 (not 320)
5. 520 ÷ 10 = 52 (correct)
6. 300 ÷ 100 = 3 (not 30)
7. 360 ÷ 2 = 180 (not 18)
8. 360 ÷ 20 = 18 (correct)

So, some of the equations are correct, while others have incorrect solutions. Make sure to double-check your calculations for accuracy.
