Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
Can you multiply fractions that have a different demonminator?
Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.
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 check you math with adding fractions?
When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly
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.
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
Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
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.
Can you multiply fractions that have a different demonminator?
Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.
Why does the equivalent fraction make adding and subtracting fractions easier?
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
Why do you have to have a common denominator?
A common denominator is needed when adding or subtracting fractions of different denominators.
What is the most important thing about adding and subtracting fractions?
Making sure the denominators are the same.
When will you need to find the multiples and factors?
When adding or subtracting fractions with different denominators and when reducing fractions to their lowest terms
how to rename fractions using LCM?
When adding or subtracting fractions with different denominators their lowest common denominator must be found first by using the LCM of their denominators
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 first thing you should look for when adding or subtracting fractions or mixed numbers?
common denominators.
