To solve this problem, we need to calculate a percentage of a percentage of a number. This involves converting percentages into decimals or fractions and performing multiplication.
First, convert the given percentages into their decimal forms:
The phrase "of" in mathematics signifies multiplication. So, the expression "\(20\%\) of \(125\%\) of $160$" can be written as:
\(0.20 \times 1.25 \times 160\)
Calculate the result step-by-step:
\(1.25 \times 160 = 200\)
\(0.20 \times 200 = 40\)
Thus, \(20\%\) of \(125\%\) of $160$ is $40$.
By how much is 80% of 40 greater than \(4\over5\) of 25?
