Answer 1

$1\frac{1}{2}= \frac{3}{2}\; \; ,\; \; 1\frac{1}{3} =\frac{4}{3}\; \; ,\; \; 1\frac{1}{4} = \frac{5}{4}\; \; ,\; \; 1\frac{2}{3}= \frac{5}{3}\; \; ,\; \; 1\frac{3}{4}=\frac{7}{4} \\\\2\frac{1}{4}= \frac{9}{4}\; \; ,\; \; 3\frac{1}{5}=\frac{16}{5}\; \; ,\; \; 8\frac{1}{3} =\frac{25}{3} \; \; ,\; \; 2\frac{2}{5}=\frac{12}{5} \; \; ,\; \; 9\frac{5}{7}= \frac{68}{7}$

Answer 2

Converting Mixed Numbers to Improper Fractions

To convert the given mixed numbers to improper fractions, we can use the following formula:

Improper Fraction = (Whole Number * Denominator) + Numerator / Denominator

Let's convert each mixed number to an improper fraction:

1. 1 1/2: Improper Fraction = (1 * 2) + 1 / 2 = 3/2

2. 1 1/3: Improper Fraction = (1 * 3) + 1 / 3 = 4/3

3. 1 1/4: Improper Fraction = (1 * 4) + 1 / 4 = 5/4

4. 1 2/3: Improper Fraction = (1 * 3) + 2 / 3 = 5/3

5. 1 3/4: Improper Fraction = (1 * 4) + 3 / 4 = 7/4

6. 2 1/4: Improper Fraction = (2 * 4) + 1 / 4 = 9/4

7. 3 1/5: Improper Fraction = (3 * 5) + 1 / 5 = 16/5

8. 8 1/3: Improper Fraction = (8 * 3) + 1 / 3 = 25/3

9. 2 2/5: Improper Fraction = (2 * 5) + 2 / 5 = 12/5

10. 9 5/7: Improper Fraction = (9 * 7) + 5 / 7 = 68/7

Converting Improper Fractions to Mixed Numbers

Now, let's convert each improper fraction to a mixed number:

1. 3/2: Mixed Number = 1 1/2

2. 4/3: Mixed Number = 1 1/3

3. 5/4: Mixed Number = 1 1/4

4. 5/3: Mixed Number = 1 2/3

5. 7/4: Mixed Number = 1 3/4

6. 9/4: Mixed Number = 2 1/4

7. 16/5: Mixed Number = 3 1/5

8. 25/3: Mixed Number = 8 1/3

9. 12/5: Mixed Number = 2 2/5

10. 68/7: Mixed Number = 9 5/7

These are the improper fractions and their corresponding mixed numbers.
