What is $0.8\%$ of $125\%$ of $8128$? Express your answer as a decimal.

Andre45 [30]

Answer:

Step-by-step explanation:

To solve this kind of problem, we must remember that the word "of" means multiplication in math language, and all percentages numbers can be expressed as a fraction where the denominator is 100. Applying all this, we have

$0.8\%\times 125\%\times 8128\\\frac{0.8}{100}\times \frac{125}{100} \times 8128\\ 0.008(1.25)(8128)=81.28$

Therefore, all those percentages of 8128 results in 81.28
