Understanding Unsimplified Fractions
To convert 1 1/4 into an unsimplified form, you essentially want to express the mixed number as an improper fraction. This involves converting the whole number into a fraction that has the same denominator as the fractional part and then adding the two fractions together. To do this, multiply the whole number (1) by the denominator of the fractional part (4), which equals 4, and then add the numerator of the fractional part (1), resulting in a numerator of 5. Therefore, 1 1/4 as an improper fraction is 5/4.
Step-by-Step Calculation
- Multiply the whole number (1) by the denominator (4): 1 * 4 = 4.
- Add the result to the numerator of the fractional part (1): 4 + 1 = 5.
- Write the result (5) over the original denominator (4): 5/4.
This new fraction, 5/4, is the unsimplified form of 1 1/4. This process is straightforward and can be applied to convert any mixed number to an improper fraction.
