What number is 80% of 50% of 20% of 400?

Translate to an equation and then solve.

Solution: “What number” translates into a variable, I’ll use “n”. The word “is” translates into an equals sign. The three percents get translated into their decimal equivalents: .8, .5, and .2. The “of’s” gets translated into multiplication signs. And 400 is an integer which needs no translation. So the equation looks like this:

n = .8 x .5 x .2 x 400

n = 32
