Is there a specific rule to follow when dividing simplified fractions? i mean if you were to have the numerator and demoninator you divide them by two four? or is it optional?

Answer:

Step-by-step explanation:

This method consists of multiplying the numerator of the first fraction by the denominator of the second fraction and then writing the answer in the resulting fraction’s numerator.

Next, we multiply the denominator of the first fraction by the numerator of the second fraction, and then write the answer in the resulting fraction’s denominator*.

Lastly, we simplify the final fraction.

For example, in order to divide the fraction

dividing fractions

We multiply the numerator of the first fraction (3) by the denominator of the second fraction (10). This gives us the numerator for the final fraction: 3 x 10 = 30.

Next, we multiply the denominator of the first fraction (4) by the numerator of the second fraction (6). This gives us the denominator of the final fraction: 4 x 6 = 24.

dividing fractions

The last step is to simplify the fraction. Since both numbers are multiples of 6, we can divide the numerator and denominator by 6.

30 ÷ 6 = 5

24 ÷ 6 = 4

Therefore, the result of the division is 5/4.

Method 2 of dividing fractions: Inverting and multiplying

Step 1: Invert the second fraction. That is, swap the numerator for the denominator.

Step 2: Simplify any numerator with any denominator.

Step 3: Multiply across.

For example, we are going to divide:

dividing fractions

Step 1: We invert the second fraction 6/4. This becomes 4/6.

Step 2: We simplify the numerators with the denominators.

Numerators are:

12 = 2 x 2 x 3

4 = 2 × 2

Denominators are:

5 = 5

6 = 2 × 3

We can simplify both from numerator and denominator a 2 and a 3. We call this process “cross canceling” if one numerator has a common factor with the other denominator.

And we multiply across:

The diagram below represents the measurements of Jennie’s yard. The yard’s width is x feet shorter than its length. If the area of the yard is 540 square feet, how many feet shorter than the length is the width? A yard with a length of 30 feet and a width of (30 minus x) feet. Which equation represents the scenario? 30 + (30 – x) = 540 540 – 30 = 30 – x 30(30 – x) = 540 540 – (30 – x) = 30
