What is the first step in multiplying a fraction by a whole number?

To multiply a fraction by a whole number, the first step is to convert the whole number into a fraction by placing it over the number 1. This way, you can easily multiply the numerator of the fraction by the whole number.

How do you convert a whole number into a fraction?

To convert a whole number into a fraction, you need to express the whole number as a fraction by placing it over the number 1. For example, if you have the whole number 5, you can convert it into a fraction as 5/1. This is because any whole number can be written as the number itself divided by 1.

Why is the numerator of the fraction multiplied by the whole number?

When multiplying a whole number by a fraction, you are essentially multiplying the whole number by the numerator of the fraction. This is because the numerator represents the number of parts you are considering, and multiplying it by the whole number gives you the total number of parts you have. It's a way of scaling up the fraction by the whole number to find the result of the multiplication in terms of the total units or parts.

What happens to the denominator of the fraction when multiplying by a whole number?

When you multiply a fraction by a whole number, the denominator remains the same. Multiplying by a whole number only affects the numerator of the fraction. The product will have the same denominator as the original fraction.

Can the whole number be simplified before multiplying? Why or why not?

No, whole numbers cannot be simplified before multiplying because they are already in their simplest form. Whole numbers do not have any fractional or decimal parts that can be simplified further. When you multiply whole numbers, you are simply performing the operation without needing to simplify them first.

How do you simplify the fraction if the numerator and denominator have common factors?

To simplify a fraction when the numerator and denominator have common factors, you can divide both the numerator and the denominator by the greatest common factor (GCF) of the two numbers. This process is known as reducing the fraction to its simplest form. By dividing both numbers by their GCF, you can obtain a fraction that cannot be reduced further and represents the same ratio as the original fraction.

What is the final step in multiplying a fraction by a whole number?

The final step in multiplying a fraction by a whole number is to simplify the resulting fraction, if necessary, by finding the greatest common factor (GCF) between the numerator and denominator and dividing both by it. This step helps to reduce the fraction to its simplest form.

Can the product of a fraction and a whole number be an improper fraction? Why or why not?

Yes, the product of a fraction and a whole number can result in an improper fraction. This can happen when the whole number is multiplied by a proper fraction that has a numerator greater than its denominator, resulting in a product that is larger than 1 and thus an improper fraction. The numerator of the resulting fraction will be the product of the whole number and the numerator of the proper fraction, while the denominator will remain the same.

How can you check your answer after multiplying a fraction by a whole number?

To check your answer after multiplying a fraction by a whole number, you can reverse the operation by dividing the result by the same whole number you originally multiplied by. If the quotient you get is equal to the original fraction you started with, then your multiplication was correct. This step ensures that your initial calculation was accurate and helps you confirm the correctness of your answer.

Can you provide an example problem of multiplying a fraction by a whole number?

Sure! An example problem of multiplying a fraction by a whole number is: What is 3/4 of 8? To solve this problem, you would first convert the whole number 8 to a fraction by writing it as 8/1. Then, you would multiply the fraction 3/4 by the fraction 8/1, which results in (3*8)/(4*1) = 24/4 = 6. Therefore, 3/4 of 8 is equal to 6.
