4 divided by 1/2 ??????
1/4 divided by 1/3 ?????
3 3/4 divided by 1/3 ????
Thank you to everyone who has been helping me!!
4 /(1/2)
multiply top and bottom by 2
8 /(2/2)
or
8
================
(1/4) /(1/3) multiply top and bottom by 3
(3/4) / (3/3)
or
3/4
=========================
(15/4) / (1/3)
again top and bottom by 3
45/4 = 11 1/4
4 divided by 1/2
Invert the divisor and multiply.
4 * (2/1) = 8

To solve these division problems involving fractions and mixed numbers, we can follow a general process:
1. Convert mixed numbers to improper fractions (if applicable).
2. Keep the first fraction as it is and change the division sign to multiplication.
3. Flip the second fraction (reciprocal).
4. Multiply the two fractions together.
5. Simplify (if necessary) by reducing or converting to a mixed number.
Let's go through each problem using this process:
1. 4 divided by 1/2:
- Convert 4 to an improper fraction: 4/1.
- Keep the first fraction (4/1) as it is and change the division sign to multiplication.
- Flip the second fraction: 1/2 becomes 2/1.
- Multiply: (4/1) * (2/1) = 8/1.
- The result is 8.
2. 1/4 divided by 1/3:
- Keep the first fraction (1/4) as it is and change the division sign to multiplication.
- Flip the second fraction: 1/3 becomes 3/1.
- Multiply: (1/4) * (3/1) = 3/4.
- The result is 3/4.
3. 3 3/4 divided by 1/3:
- Convert the mixed number 3 3/4 to an improper fraction: 15/4.
- Keep the first fraction (15/4) as it is and change the division sign to multiplication.
- Flip the second fraction: 1/3 becomes 3/1.
- Multiply: (15/4) * (3/1) = 45/4.
- Simplify: 45/4 is an improper fraction, which can be converted to a mixed number as 11 1/4.
- The result is 11 1/4.
Remember, when multiplying fractions, you multiply the numerators (top numbers) together and the denominators (bottom numbers) together. Additionally, don't forget to simplify or convert to mixed numbers as needed.
