What do you when your subtracting fractions with unlike denominators and when you subtract your numerator is zero?

If the numerator of a fraction is zero, it doesn't need to be converted to a common denominator because its value is actually zero (zero by anything divided is zero), so you should drop it from the equation.

What are the rules for subtracting fractions?
You multiply the fractions until the denominators are equal. Then, you subtract.
What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
When adding or subtracting fractions do you change the numerator?
you subtract the numerator but the denominator stays the same.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How is finding the LCM revelant when adding and subtracting fractions?
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
Why does the equivalent fraction make adding and subtracting fractions easier?
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
How is subtracting decimals is like subtracting fractions?
because you subtract the 2 numerators and then 2 denominators right across just like that :)
How do you subtract improper fractions with different denominators?
It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).
How do you subtract mixed fractions when they have the same denominator?
The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.
What are the rules in subtracting similar fraction?
If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
Can you explain adding and subtracting fractions with like denominators?
When you add or subtract fractions with like denominators, you just add or subtract the numerators and put them over the same denominator. For example, 3/5 - 2/5 = (3 - 2)/5 = 1/5
What do you do when you're going to subtract fractions but the numerator is the same?
its the same as working with integers. + and a + = + -and a - = + + and a - = - - and a + = - eg. 4/4 - - 3/4= 4/4 + 3/4= 1 3/4 1/2+ - 3/10 = 2/10= 1/5
