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 do you add improper fractions?
If the denominators are different, find a common denominator, convert the fractions to equivalent fractions with the same denominator, proceed with adding the numerators, put that total over the denominator, simplify if possible. If the denominators are the same, skip the conversion, proceed with adding the numerators, put that total over the denominator, simplify if possible.
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.
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 is the definition of adding and subtracting fractions with unlike denominators?
What is the definition of Adding and Subtracting Like 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.

What does adding fractions mean?
it means to leave the denominators the same and add the numerators
When adding fractions with like denominators how do you convert?
When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.
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.
What is the trick when adding fractions?
The trick to adding fractions is three simple steps. First, make sure the bottom numbers (the denominators) are the same. Secondly, add the top numbers (the numerators), put the answer over the denominator. Finally, simplify the fraction if need be.
Does adding numerators and denominators work in fraction addition?
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
How is multiplying fractions different from adding fractions?
When multiplying fractions, the numerators (top numbers) are multiplied together and put as the numerator over the denominators (bottom numbers) multiplied together.When adding fractions, they must both have the same denominator - the fractions are made into equivalent fractions with a common denominator; then the numerators are added together and put over the same common denominator.In both cases of multiplication and addition, the resulting fractions are reduced to simplest form.
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.
How do you add improper fractions?
If the denominators are different, find a common denominator, convert the fractions to equivalent fractions with the same denominator, proceed with adding the numerators, put that total over the denominator, simplify if possible. If the denominators are the same, skip the conversion, proceed with adding the numerators, put that total over the denominator, simplify if possible.
What did you learn from adding and subtracting fractions?
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
Why do you change mixed numbers to improper fractions before multiplying and dividing?
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
What is the rule in adding fractions having the same denominator?
Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
