To find the square of 1 3/5, convert the mixed number to an improper fraction (8/5), square it to get 64/25, which is equal to 2 14/25 as a mixed number or 2.56 as a decimal.
Step-by-step explanation:
The correct answer is option: The square of 1 3/5 is calculated by first converting the mixed number to an improper fraction. The mixed number 1 3/5 is equal to 8/5 when converted.
Squaring the fraction means multiplying the fraction by itself, resulting in (8/5) * (8/5) = 64/25, which equals to 2 14/25. If we need the answer as a decimal rounded to two decimal places, we divide 64 by 25 to get 2.56.
The square of 1 3/5 can be found by multiplying the number by itself. First, convert the mixed number to an improper fraction: 1 3/5 = (5 * 1 + 3)/5 = 8/5. Then, square the improper fraction: (8/5) * (8/5) = 64/25. Finally, simplify the fraction if needed: 64/25 = 2 14/25. Therefore, the square of 1 3/5 is 2 14/25.
