Does the numerator or denominator change when adding or subtracting?
numerator
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.
Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
How can you change fractions into decimal?
You divide the numerator by the denominator.
How do change fractions into a deciml?
Divide the numerator by the denominator
Does the numerator or denominator change when adding or subtracting?

When adding or subtracting fractions what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
Do you have to change the denominators when multiplying fractions?

What is the most important thing you can say about adding or subtracting fractions?
the most important thing is to change the denominators so u can make common denominators
How can you change fractions into decimal?
You divide the numerator by the denominator.
How do change fractions into a deciml?
Divide the numerator by the denominator
How sustract fractions?
Determine the lowest common denominator. Multiply the numerator and denominator of each fraction by a number that will result in the denominator becoming the LCD. The purpose for multiplying both the numerator and denominator is that any number divided by itself = 1, and when you multiply something by 1, you don't change it. When subtracting two fractions with the same denominators, the first numerator minus the second numerator equals the numerator of the result, and the result has the same denominator (the LCD). Simplify.
How do you change a fractions to a decamals?
To change fractions into decimals divide the numerator by the denominator as for example 3/4 = 0.75
Do you change a mixed number into an improper number while adding and subtracting?
you do what makes sense given the numbers, if the fractions work out beautifully, you can just leave them as mixed numbers, otherwise it's best to keep them as improper fractions
How do you change equivalent fractions to decimals?
Divide the denominator into the numerator.
Do you change fractions 2 like fractions when adding them?
Yes, you must.
