When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
What are the characteristics of improper fractions?
Improper fractions have numerators that are greater than or equal to their denominators.
How do you add two fractions together?
If the denominators are equal, you just add the numerators. For example, 1/10 + 3/10 = 4/10. If the denominators are different, you must first (1) find a common denominator, and (2) convert both frations to that common denominator.
Is it possible for two fractions greater than 1 that have different numerators and denominator to be renamed as the same mixed number?
Yes, it is possible for two fractions greater than 1 with different numerators and denominators to be renamed as the same mixed number. This can happen when the fractions are equivalent, meaning they represent the same value. To determine if two fractions can be renamed as the same mixed number, you need to simplify them to their simplest form and then compare them to see if they are equal.
Is eight tenths greater than six tenths?
Yes. Look at the denominator (10). If the denominators of both fractions are equal than go with the higher numerator as the greater number
