The way I do this quickly in my head is:
What is 1/10 of 80? Simply move the decimal one place to the left. 1/10 of 80 = 8.0
Now, since we actually need 7/10, just multiply by 7.
So, 56.

The easiest way to think of this is 7/10 = 70%
70% (or 0.7) times 80 = 56

To get 70% of 80 (ie, 7 tenths of it), simply multiply 80 by .70
80 * 7/10 = 56
