Writing Mixed Numbers as Improper Fractions

To write a mixed number as an improper fraction, you need to convert the whole number and the fraction into a single fraction. Here's how you can do it:

1. Multiply the whole number by the denominator of the fraction. 2. Add the result to the numerator of the fraction. 3. Write the sum as the numerator of the new fraction, and keep the denominator the same.

For example, let's say we have the mixed number 2 3/4. To convert it into an improper fraction:

1. Multiply the whole number (2) by the denominator of the fraction (4): 2 * 4 = 8. 2. Add the result (8) to the numerator of the fraction (3): 8 + 3 = 11. 3. Write 11 as the numerator of the new fraction, and keep the denominator (4) the same.

Therefore, 2 3/4 can be written as the improper fraction 11/4.

Examples of Writing Mixed Numbers as Improper Fractions

Here are some examples of writing mixed numbers as improper fractions:

1. 3 2/5: - Multiply the whole number (3) by the denominator of the fraction (5): 3 * 5 = 15. - Add the result (15) to the numerator of the fraction (2): 15 + 2 = 17. - Write 17 as the numerator of the new fraction, and keep the denominator (5) the same. - Therefore, 3 2/5 can be written as the improper fraction 17/5.

2. 7 1/8: - Multiply the whole number (7) by the denominator of the fraction (8): 7 * 8 = 56. - Add the result (56) to the numerator of the fraction (1): 56 + 1 = 57. - Write 57 as the numerator of the new fraction, and keep the denominator (8) the same. - Therefore, 7 1/8 can be written as the improper fraction 57/8.

3. 2 14/17: - Multiply the whole number (2) by the denominator of the fraction (17): 2 * 17 = 34. - Add the result (34) to the numerator of the fraction (14): 34 + 14 = 48. - Write 48 as the numerator of the new fraction, and keep the denominator (17) the same. - Therefore, 2 14/17 can be written as the improper fraction 48/17.

These are just a few examples of how to write mixed numbers as improper fractions. The process remains the same for any mixed number you encounter.
