How do you solve all fractions problems?
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
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.
Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
Define equivalent fractions?
Equivalent fractions are fractions that have the same value as another fraction.
Why is it helpful to find common factors for 2 nummbers?
This can be especially helpful if you are adding or subtracting fractions, so the bottom number on both fractions will be the same
How are adding and subtracting fractions similar?
Subtracting a fraction is the same as adding its negative.
What is the common denononator?
In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.
Before adding or subtracting Why are fractions turned into like fractions?
They have to have the same denominator.
What are the rules for adding fractions?
Ensure that the denominators are the same when adding or subtracting fractions.
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same
What is the rule for subtracting fractions?
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
What do you notice about the denominator when subtracting like fractions?
By the definition of like fractions, the denominators are the same.
How do you subtract fractions with negative fractions?
Subtracting a negative fraction is the same as adding its positive equivalent.
Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
How can you get the simplest form for subtracting fractions?
just divide the number on the top and the number at the bottom with the same number. keep on dividing until you can't divide anymore
How do you find a multiple when subtracting fractions?
Same as adding, multiplying, and dividing.
