Question

80% of what is 16 show your work

Answer 1

Its easy, I'll show you how to do this kind of a question. 

Use this formula 

Part over whole equals percentage over 100. Because any percentage is that number over 100, for an example, 37% is really also 37 / 100 

Part / whole = % / 100% 

So you have to know 3 of the 4 missing items.  

We already know 16 is the part, we need to know the whole. We also know it is 80 % so it is 80/100 

So we put it this way 

16 / x (unknown whole) = 80/100 

We cross multiply  

80x = 1600 

divide both by 80  

x = 20 

Your welcome

Answer 2

of = multiplication in mathematical terms. So, lets work out this problem until we get your answer

80(16)
80÷100 = 0.8
0.8(16) =
Your result is: 12.8
