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 find equivalent fractions?
first simplify the fraction then multiply the denominators times the numerators and see if they are equal
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.
Which is larger 0.4 or 0.6?
0.6 is larger than 0.4.The reason is that we can write 0.6 as 6/10 and 0.4 as 4/10,when the denominators of two fractions are equal then the fraction with the highest numerator will be the highest.
What are fractions that are equal in value but may have different numerators and denominators?
Equivalent fractions.
What are fractions that are equal in value but have different numerators and denominators?
They are known as equivalent fractions
How do you know when two fractions are equal?
If the denominators (bottom numbers) are not equal, making equivalent fractions of them so that the denominators are equal. With the denominators equal if the numerators (top numbers) are equal, then the fractions are equal.
Fractioins that are equal in value but may have different numerators and denominators?
equal fractions
Can two fractions with the same numerator and different denominators be equal?
Only if the numerator is zero,
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 rules for subtracting fractions?
You multiply the fractions until the denominators are equal. Then, you subtract.
What are the characteristics of improper fractions?
Improper fractions have numerators that are greater than or equal to their denominators.
When is the lcd of two fractions equal to product of denominators?
When the denominators are relatively prime, that is, they have a GCF of 1.
What are three fractions with different denominators that are equal toone half?
7/14, 4/8, 3/6
How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
Two or more fractions that are equal is called what?
In actual problems, we convert two (or more) fractions so that they have equal denominators.
