A mixed number combines a whole number and a proper fraction (e.g., 2¾ = two and three-quarters). Converting between mixed numbers, improper fractions, and decimals is essential for measurement, cooking, and arithmetic operations.
Guide étape par étape

- 22¾ = (2×4 + 3)/4 = 11/4
- 3Improper to mixed: divide numerator by denominator; quotient is whole, remainder is new numerator
- 4To decimal: divide the fraction part: 2¾ = 2 + 3/4 = 2 + 0.75 = 2.75
