What is the square of 1 3/5 (one and three fifths)?

Explanation:
When squaring a mixed number, it’s simplest to convert it to an improper fraction first. 1 3/5 equals 8/5. Squaring gives (8/5)^2 = 64/25. Converting back to a mixed number: 64/25 = 2 with a remainder of 14, so it’s 2 14/25. This is the same as 2.56 in decimal form, since 14/25 = 0.56.
