Why is it easy to add or subtract fractions with the same numbers with the same denominator?

Because then, you will just basically be doing normal addition or subtraction. Also, the denominators would be the same, so you wouldn't have to find a LCM.

What are the steps to subtracting fractions?
Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.
Why is it easy to subtract and add with the fraction that has the same donominator?
When adding or subtracting fractions with the same denominator, it is easier because we can simply add or subtract the numerators and keep the denominator the same. The denominators are already equal, so no additional calculations or adjustments are necessary. This simplifies the math and makes it easier to compute the result.
What is the easy way to add or subtract fractions?
Unfortunately, there is no "easy" way to add and subtract fractions, really-you always have to find a common denominator. If you can't be bothered finding one right away, it may at least be a bit easier to save this step for the end. For example, instead of finding a common denominator before adding 4 / 13 and 22 / 42, start by simply multiplying the fractions by 42 / 42 and 13 / 13, respectively. This gives us 168/546 + 286/546 = 454/546. You can see that these are divisible by 2, so we have 227 / 273. (Note that this is a somewhat situational example, in that the fraction cannot be reduced from 546 if some numbers are added, e.g. 546 is not divisible by 5, so 5/546 could be a final answer.)
How do you subtract 2 binary numbers?
An easy way is to convert them to decimal, subtract, then convert the answer back to binary.
How do you arrange fractions 2-3 5-6 7-12?
You convert them to a common denominator. Then, it will be easy to compare.

Order rational numbers?
Rational numbers are (basically) fractions. You can compare any two fractions by converting them to fractions with a common denominator, and then comparing their numerators.You can also convert them to their decimal equivalent (just divide numerator by denominator); that also makes them fairly easy to compare.

What are the advantages of writing fractions in deciamal form?
Fractions in decimal form are easy to compare and to add and subtract from one another.
How do you order ratios from least to greatest?
it's pretty easy you wold get a common denominator then do what you do with fractions

Why you must have a common denominator to add or subtract fractions?
To get the correct answer. Look at 1/2 - 1/3. Most people can't tell what the answer is by looking at it. But if you rewrite it as 3/6 - 2/6, it's easy to see that the answer is 1/6.

Who uses the least common multiple?
Anyone who is trying to add or subtract fractions.
How can one multiply fractions without a calculator?
You multiply the numerators across and put that as the numerator of your answer, then multiply the denominators of the fractions across the put that as the denominator of your answer. It is very easy.
How can you use a model to subtract fractions with like denominators?
No. You just have to change it so the denominators are the same, and then it's easy from there!
How do you arrange fractions 2-3 5-6 7-12?
You convert them to a common denominator. Then, it will be easy to compare.
