To find out what number 50% of it equals 80, you can set up the equation: 0.5 * x = 80, where x is the number we want to find.
Now, to solve for x, we can rewrite the equation:
x = 80 / 0.5
Calculating this gives us:
x = 160
So, 50% of 160 is 80. This means that if you take half of 160, you will arrive at 80.
