3/4, -7/10, -3/4, 8/10 least to greatest

-3/4 < -7/10 < 3/4 < 8/10

I figured this out by dividing the numerator by the denominator to get a percentage. So

-3 divided by 4 = -75%

-7 divided by 10 = -70%

3 divided by 4 = 75%

and 8 divided by 10 = 80%

Converting to percentages really helps a lot with fraction, especially when ordering them from least to greatest :)

Hope this helps :)

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

-7/10 is -70%

-3/4 is -75%

3/4 is 75%

8/10 is 80%

Hope that this helps you out! :3
