Because to add fractions, the denominators must be equal.
Improper fractions have numerators that are greater than or equal to their denominators.
first simplify the fraction then multiply the denominators times the numerators and see if they are equal
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.
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.
Equivalent fractions.
They are known as equivalent fractions
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.
equal fractions
Only if the numerator is zero,
Because to add fractions, the denominators must be equal.
You multiply the fractions until the denominators are equal. Then, you subtract.
Improper fractions have numerators that are greater than or equal to their denominators.
When the denominators are relatively prime, that is, they have a GCF of 1.
7/14, 4/8, 3/6
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.
In actual problems, we convert two (or more) fractions so that they have equal denominators.
