Trying to help my son in Fractions. Need to know how to figure out the fractions from least to greatest 3/4; 14/16; 15/25; 17/20; 3/18

use a calculator. Do each fraction.

3/4 = 0.75

so on and so forth

ah. In that case, least common denominator.

from what I can see... the least common denominator is 120.

so...

3/4 = 90/120
14/16 = 105/120
15/25 = 72/120
17/20 = 102/120
3/18 = 20/120
