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.
How do you add and subtract frations with a whole number with a fraction?
Express the mixed fraction as an improper fraction and then proceed as you would with ordinary fractions. If the answer is an improper fraction, then remember to convert to a mixed fraction.
