What is one fifth of 20 percent?

Answer 1

Notice that

-- one fifth of 20 pounds of topsoil is 4 pounds of topsoil,

-- one fifth of 20 cows is 4 cows,

-- one fifth of 20 miles of rope is 4 miles of rope,

-- one fifth of 20 acres of land is 4 acres of land,

-- one fifth of 20 bushels of tomatoes is 4 bushels of tomatoes, and

-- one fifth of 20 dozen cookies is 4 dozen cookies.

Once you notice this, and begin to pick up the pattern, you might be tempted to guess

that one fifth of 20 percent is 4 percent.

And you'd be correct.
