How do you add mixed fractions with another mixed fraction?
You convert them both to improper fractions by multiplying the denominators by the whole number and then adding the numerator to it. This number goes in the numerator and the denominator stays the same. Then you do this for the other fraction, making sure that the denominators of each fraction are equivalent. Then add the fractions as normal.
When adding or subtracting fractions do you change the numerator?
you subtract the numerator but the denominator stays the same.
Do you have to have the same denominator when you subtract fractions?
Yes, but the numerator is different,same as adding fractions
How do you add fractions with same numerator?
if it has a denominator
How can you add similar and dissimilar fractions?
Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.
Why when adding do you not add the numerator or the denominator?
Do not add the denominators together. Though keep in mind that both denominators must be the same to add to fractions together.

Do you need to add whole number when adding fractions?
yes you do, first you make the denominators the same, then you add the numerator after that you can regroup any "extras" into those whole numbers.
How do you compare add fractions?
add by adding
When you are subtracting fractions and you need to borrow from the numerator do you add the whole number to the numerator?
Yeah banana
When adding or subtracting fractions do you have to have the numerator the same or denominator?
The denominators must be the same, the numerators can be different.

How is multiplying fractions by a whole number is different from adding adding and subtracting fractions with like denominators?
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
How is adding like fractions and adding unlike fractions the same?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
