put three fourths - 7/10 - 3/4 8/10 in least to greatest

Alright!

Three Fourths is 3/4.

So our numbers are ...

3/4, - 7/10, - 3/4, 8/10

We'll need a common denominator to compare the fractions. A common denominator is simply a number which they are all divided by.

So! The one that jumps out the most is 40, because it is the lowest number that both 10 and 4 are divisible by.

In order to get a common denominator you must multiply it by that multiple.

3/4 * 10/10 = 30/40

-7/10 * 4/4 = - 28/40

-3/4 * 10/10 = - 30/40

8/10 * 4/4 = 32/40

Larger negative answers are smaller. Think of it in terms of a number line. As you go to the left the negative numbers get bigger and bigger, and thus smaller and smaller.

Least to greatest would look like this:

-30/40, - 28/40, 30/40, 32/40

-3/4, - 7/10, 3/4, 8/10

These are in least to greatest.
