Example 1/5 plus 1/4. That's like 1 pie plus 1 cake, you can't do it. But if you convert to the " Lowest common multiple denominator (20) " then you have 4/20 plus 5/20. Now you are adding 4 buns to 5 buns and you can do that. Answer 9/20. Another way is to convert to decimal equivalents: 0.2+ 0.25 = 0.45 (which is 45/100, or 9/20)
What else can I help you with?
How do you do improper fractions?
Well let's say that you have the mixed number one and a half. The one counts as 2 two's. Then you add the two two's with the other two that made up the half and get three over two.
Can bubbles be made with water?
Bubbles cannot just be made with plain water; you need to add soap or something else like that. Shampoo, bubble bath, soap etc...
How do you use the slide method?
Well using a slide method this method you will be using a L but its going to be a capital L and you enter what ever number you have and you can use this method for fractions,decimals,least common multiple,greatest common factor,and other thing if your teacher did this with you please add more details to this anymore questions just comment and tell me cause I will teach you
Why is HCl added before titration?
Without the specific details, one cannot be sure, but this is probably a back titration. You add a known amount of acid to your unknown, then titrate to measure how much has not reacted. You can then calculate how much of your first chemical must have been present.
What are facts about separating salt from pepper?
Salt can dissolve while pepper cannot. So one way to separate salt and pepper would be to add water until all the salt dissolved and pouring the liquid out. Then, let the salt water solution evaporate, leaving salt behind! =D
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.
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.
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.
Adding unlike fractions?
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.
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
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.
How does using fraction strips with like denominators make it possible to add fractions with unlike denominators?
because they are the same number
Why does the equivalent fraction make adding and subtracting fractions easier?
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
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.
Why do fractions need to have unlike denominator before you add or subtract them?
The question is based on a complete misunderstanding of what is required. Unlike denominators are NOT required!
Does adding numerators and denominators work in fraction addition?
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
Do you add denominators in fractions?
No.
How do you add three fractions with unlike denominators?
-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.
