What is 1 minus 1/5?

Explanation:
Subtracting a fraction from a whole involves making the denominators match. Turn the whole into fifths: 1 equals 5/5. Then subtract: 5/5 − 1/5 = 4/5. So the result is 4/5. Think of a whole divided into five equal pieces and removing one piece—the remaining pieces are four out of five. (That’s 4/5, or 0.8 in decimal form.)
