How do you subtract mixed numbers that do not have the same denominator?

Find a common denominator of the fraction parts (the least common denominator is the popular choice). If the fraction part of the subtrahend is bigger than that of the minuend, you need to subtract 1 from the integer (whole number) part of the minuend and add it (as a fraction) to the fraction part. For example, 5 3/7 becomes 4 10/7. Then you can subtract the fraction parts by subtracting the numerators, and subtract the integer parts, provided the integer part of the minuend is greater than or equal to that in the subtrahend.
If not, reverse the roles of the minuend and subtrahend and use the above method to subtract, then make the sign of the difference negative.

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.
How do you subtract fractions with a common denominator?
If the two bottom numbers are the same, you will carry that same number over to the denominator in the answer. To get the numerator (top number) simply subtract the two numerator and place the number over the answer denominator.
How do you convert mix numbers?
multiply the denominator by the whole number, then add the numerator, the denominator is the same as the mixed numbers denominator
Can you subtract a fraction with the same denomintor and get a different denominator?
Only after simplification. If you subtract numbers with the same denominator, you have to put the original denominator in the result, but you can later simplify this, in some cases. A simple example: 3/4 - 1/4 = 2/4. Same denominator, but this can be simplified to 1/2.
How do you write mixed numbers into fractions?
You multiply the denominator by the whole number the add the numerator and you keep the denominator the same.
How do you subtract fractions without mixed numbers?
First, turn the fraction into a improper fraction. Then find a common denominator between the two numbers. After this, subtract strait across, but leave the denominator the same.
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 do adding and subtracting mixed numbers means?
To combine the fractions or subtract the fractions. Same method with mixed numbers.
How do you convert mix numbers?
multiply the denominator by the whole number, then add the numerator, the denominator is the same as the mixed numbers denominator
How do you add mixed numbers that do not have the same denominator?
You re-scale them so that the denominators are the same.

When you subtract fractions do you subtract the denominator?
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
What do you have to do first before adding and subtracting mixed numbers?
look at the denominator see if it is the same as the other denominator or see if it is the same number at the bottom of each number.
How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.
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.
