You basically just see the denominator, try to convert it into 100. Then create a number line from 1-100. Then use the numerator of the converted fraction and place it on the number line.
lets say you want to find 3/4 on a number line first you split the line into 4 pieces then you mark 0/4 1/4 2/4 3/4 4/4 the third one would be 3/4 I hope this helped you!
