Questions & Answers

Q: How do you divide a fraction by a whole number?

To divide a fraction by a whole number, convert the whole number to a fraction by placing it over 1. Then, use the keep change flip principle and multiply the numerators and denominators.

Q: Can you simplify the resulting fraction after dividing?

Yes, if the resulting fraction can be simplified, you should simplify it. Find the greatest common divisor of the numerator and denominator and divide them by it to simplify the fraction.

Q: Are all the answers in the video in fractional form?

No, some answers can be simplified to whole numbers, while others remain as fractions or improper fractions. It depends on the numbers being divided.

Q: How can you convert an improper fraction to a mixed number?

There are two methods demonstrated in the video. One is to divide the numerator by the denominator and express the remainder as a fraction. The other method is to use long division to find the quotient and remainder.
