Put the fraction in least to greatest denomenator then put them in order me 1/2 3/4 1/5 7/10 me

Working with fractions, you'll need to find the least common denominator (LCD). In this case, the LCD is 20.

Rewriting the four given numbers to the LCD, you would get:

10/20, 15/20, 4/20, and 14/20.

Now, you just organize it from least to greatest as:

4/20 < 10/20 < 14/20 < 15/20.

In other words, it is:

1/5 < 1/2 < 7/10 < 3/4.
