You find a common denominator 1/2 + 1/3... need a common denominator. 6 would work and it is the smallest number that does so it is the least common denominator or LCD. 12, 24 etc also work. Let's use 6 multiply the top and bottom of 1/2, known as numerator and denominator, by 3. We multiply by 3 because we want 6 in the bottom of denominator and 2x3=6. But since we multiply the bottom by 3 we must do it to the top too. We have 3/6 = 1/2 Now it is important to know that we are multiplying 1/2 by 3/3 and 3/3 is 1. Multiply by 1 does not change anything. That is why we are allowed to do this Do the same thing with 1/3 but multiply by 2/2 and we have 2/6 now we are adding 2/6 and 3/6 which is 5/6 and we are done!

How does using fraction strips with like denominators make it possible to add fractions with unlike denominators?
because they are the same number
How can you use equivalent fractions to help you add and subtract fractions with unlike denominators?
Change each fraction to an equivalent fraction with the same denominator. 3/8+5/12= 9/24+10/24=19/24
What are example of unlike fraction?
3/4 and 5/12
How do you turn a square root into a fraction?
In most cases you cannot since the square root is an irrational number, unlike a fraction which is rational.
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 using fraction strips with like denominators make it possible to add fraction 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 is the definition to unlike denominators?
unlike denominators: the bottom number of a fraction. to have unlike denominators you must have two fractions with a different number on the bottom of each fraction.
What is a fraction with different denominators called?
Unlike or dissimilar fraction.
How do you add and subtract fractions with unlike denominators without finding a common denominator?
The fastest and surest way to do that is to have a calculator that has a fraction button. (a b/c)
What is the unlike fraction for 17and12?
Any fraction whose denominator is not 12.
in order to convert unlike fraction to like fraction we use?
denmitor
What is an unlike fraction?
i give up i have been asking this question for 9 years a unlike fraction is where you have two or more fractions and the denominators are all different
How can you use equivalent fractions to help you add and subtract fractions with unlike denominators?
Change each fraction to an equivalent fraction with the same denominator. 3/8+5/12= 9/24+10/24=19/24
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
How can the greatest common factor and least common multiple help you work with fractions?
Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.
What are example of unlike fraction?
3/4 and 5/12
