Question

I need help with this pic (least to greatest )

Answer 1

Answer: the answer is 1/4 < 1/2 < 2/3 < 5/6 if you want to know how to do it i wrote an example:)

We do this by first converting all terms into fractions, finding the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least. To find the least common denominator, simply list the multiples of each denominator (multiply by 2, 3, 4, etc. out to about 6 or seven usually works) then look for the smallest number that appears in each list.

Example: Suppose we wanted to add 1/5 + 1/6 + 1/15. We would find the least common denominator as follows…

First we list the multiples of each denominator.

Multiples of 5 are 10, 15, 20, 25, 30, 35, 40,…

Multiples of 6 are 12, 18, 24, 30, 36, 42, 48,…

Multiples of 15 are 30, 45, 60, 75, 90,….

Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list.

Therefore, the least common denominator of 1/5, 1/6 and 1/15 is 30.
