Full solution

Q. Express 33.8181 as a mixed number.
  1. Identify Whole Number and Decimal: To express 3.813.81 as a mixed number, we first identify the whole number part and the decimal part. The whole number part is the number to the left of the decimal point, and the decimal part is the number to the right of the decimal point.\newlineIn 3.813.81, the whole number part is 33, and the decimal part is .81.81.
  2. Express Decimal as Fraction: Next, we need to express the decimal part as a fraction. Since .81.81 has two digits after the decimal point, we can write it over 100100 to convert it into a fraction.\newlineSo, .81.81 as a fraction is 81100\frac{81}{100}.
  3. Simplify Fraction: Now, we simplify the fraction 81100\frac{81}{100} if possible. Since 8181 and 100100 have a common factor of 11, the fraction is already in its simplest form.\newlineSo, 81100\frac{81}{100} remains as it is.
  4. Combine Whole Number and Fraction: Finally, we combine the whole number part with the simplified fraction to form the mixed number.\newlineThe mixed number is 33 and 81100\frac{81}{100}.
