Do you add the same denominator in fractions?
To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
What is the rule for adding fractions?
When adding and subtracting fractions, the first thing to check is if the denominators are the same. If the denominators are the same, then it’s pretty easy: just add or subtract the numerators , and write the result over the same denominator
Do you add the denominator in adding fractions?
To add fractions there are Three Simple Steps: Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator. Step 3: Simplify the fraction (if possible)
Do you add the denominator if they are the same?
To ADD fractions with like or the same denominator, simply add the numerators then copy the common denominator. Always reduce your final answer to its lowest term.
What happens if a fraction has the same denominator?
If the denominators are the same, then the fraction with the greater numerator is the greater fraction. The fraction with the lesser numerator is the lesser fraction. And, as noted above, if the numerators are equal, the fractions are equivalent.
How do you add fractions step by step?
To add fractions there are Three Simple Steps:
- Step 1: Make sure the bottom numbers (the denominators) are the same.
- Step 2: Add the top numbers (the numerators), put that answer over the denominator.
- Step 3: Simplify the fraction (if possible)
What is the rule for adding fractions with unlike denominators?
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.
What is the fractional rule?
When writing down a distance measured, normally the whole inches are followed by the fractional part of an inch. For example for a distance of one and three eights of an inch measured, this would normally be written as 1 3/8.
