70 % of 80 = 70/100 x 80
= 56
So you must get 56 right, which means you can get 80 - 56 = 24 wrong.
Alternatively:
If you must get 70 % right, then you can get 100 % - 70 % = 30 % wrong.
30 % of 80 = 30/100 x 80
= 24
You can miss 24.
Another way to look at it: 70% is 0.70 as a decimal. Multiply the decimal into any number and you have it as that percentage.
80 x 0.70 = 56
