How can knowing the GCF and LCM help you when you add subtract and multiply fractions?
Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.
How can you tell a fraction is greater than another?
Two ways: If they're unlike fractions, convert them to like fractions with a common denominator and compare numerators. Convert them to decimals by dividing their denominators into their numerators and see which is greater.
Explain how using fraction strips with like denominators make it possible to add fractions with unlike denominators?
You need to answer this question because your teacher is looking for your critical thinking skills and how well you understood the lesson.
What are fraction that have same denominator called?
They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.
What are non examples of like fractions?
non examples of like fractions = fractions that are not equal in value to other fractions. For example: 1/2 and 3/4. 1/2=.5 and 3/4=.75 since .5 does not equal .75, then 1/2 & 3/4 are not "like fractions" (see below for a summary of like fractions). Additional Info.: Like fraction examples: 1/2 & 2/4 (both fractions = the decimal value .5) 1/8 & 3/24 (both fractions = the decimal value .125) A "like fraction" is a fraction that has the same decimal value as another fraction. For example: 1/2 and 2/4 both = the decimal value .5 The easiest way to create a like fraction is to use a fraction that has a decimal value of 1. Simply multiple it times another fraction to create a like fraction. For example: Using 2/2 (which = decimal value 1), you get 2/4 as follows: 2/2 * 1/2 = 2/4 = .5 Note: 2/2 is used to create the "like fraction" 2/4. 2/4 and 1/2 are the "like fractions" because they both = the decimal value .5 You can use any fraction that is = to decimal value 1, for example: 200/200 * 1/2 = 200/400 = .5 200/400 & 1/2 are the "like fractions" that both have a .5 decimal value. You should remember this fact because it is used frequently in algebra and higher math.
What do like and unlike fractions mean?
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
What the difference between like and unlike fraction?
fractions having same denominators are like fractions & others are unlike fractions
How do you add unlike fractions?
Change them to like fractions and proceed.
What is 5 over 12 in unlike and like fractions?
Like and unlike fractions only make sense when you have two [or more] fractions. One fraction, such as 5/12, is always like itself.
What is a unlike fraction?
You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
How do you order unlike fraction?
The simplest way is to convert them to like fractions, or percentages.
What are the differents types of fractions?
the different types of fractions are:-proper fractionimproper fractionmixed fraction
What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
How are like fractions and unlike fractions different?
Like fractions have the same denominator, unlike fractions don't.
What are fractions with unlike denominators mean?
The denominator is the bottom number in a fraction. Fractions like 1/3 and 1/4 have different numbers on the bottom. Those are unlike denominators.
How do you order fractions with unlike denominators?
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
What is unlike fractions?
A fraction where the denominators are different EG: 1/6 and 1/4. Like fractions are when the denominators are the same EG: 1/6 and 2/6 Hope this helped :))))
