to add fractions the denominators must be the same. when you have unlike denominators find the LCM and rename the fractions
Well first of all let's say you have one over seven and one over five ok so you multiply the denominators the bottom numbers ok so now both bottom numbers are 35 so now first let's work with 1/7 so now it's just the bottom number and now you ask yourself 7 times what equals 35 5 right so now you times five times 1 because that was your top number so now that fraction is 5/35 now let's work with the next one which is 1/5 so now u ask yourself 5 times what equals 35 7 right so you multiply 7 times 1 and get 7 so that fraction is now 7/35 so now you add 7/35 + 5/35 equals 12/35 hope that helped
in order to add fractions with different denominators, you must first find a common denominator and convert both fractions to use that number as it's base. For example, 3/4 + 2/3 The common denominator is 12 because it is the lowest number that is divisible by both of them.
To convert each fraction to use the common denominator (12) as its base, you multiply the numerator by the same as what you have to multiply the denominator by to get 12.
In this case, for the first fraction (3/4), 4*3 = 12 so you multiply 3 (numerator) by 3 to get 9; which gives you 9/12
for the second fraction (2/3), 3*4 = 12 so you multiply 2 * 4 to get 8; which gives you 8/12
Now add the numerators while holding the denominator constant. This gives you the answer of 17/12 or 1 and 5/12

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.
Fractions with different denominators are called?
unlike fractions
What are Fractions that have different denominators?
unlike fractions
How does using fraction strips with like denominators make it possible to add fractions with unlike denominators?
because they are the same number
Explain why you cannot add fractions with unlike denominators?
You can totally add fractions with unlike denominators. You have to first find the LCD (least common denominator) to make them the same denomintars. And then you can just simply add them. What you cannot do is add fractions with unlike denominators without changing them to fractions with like denominators. The reason being that you would be attempting to add fractions that are different sizes. 1/2 is not the same size as 1/3, so it would be like trying to add apples and oranges. You have to change them to a common size and that is the reason you have to find the least common denominator first. While you cannot add 1/2 and 1/3, you can add 3/6 and 2/6.
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.
How is adding like fractions and adding unlike fractions the same?
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.

How do you subtract fractions without alike denominators?
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.

What the difference between like and unlike fraction?
fractions having same denominators are like fractions & others are unlike fractions
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?

How does the least common multiple of two numbers help you add fractions?
When adding unlike fractions, find the LCM of the denominators and convert them to it.
