First make all denominator same. See this for understanding....
-3/5 -4/10 = 5 X 10 = 50 -7/15 -7/10 = 15 X 10 =150
= 10 X 5 = 50 = 10 X 15 = 150
The is denominator same. Now the number you multiple with denominator, multiple with Numerator. See this for understanding....
-3/5 -4/10 = 3 X 10 = 30 -7/15 -7/10 = 7 X 10 = 70
= 4 X 5 = 20 = 7 X 15 = 105
Now your question is -30/50, -20/50, -70/150, -105/150. There is a difference here -30/50, -20/50 is different from -70/150, -105/150.
We have to make these two denominator same again. See this for understanding....
-30/50 -20/50 = 50 X 150 = 7500
= 50 X 150 = 7500
-70/150 -105/150 = 150 X 50 =7500
= 150 X 50 = 7500
The denominator same. Now the number you multiple with denominator, multiple with Numerator. See this for understanding....
-30/50 -20/50 = 30 X 150 = 4500
= 20 X 150 = 4500
-70/150 -105/150 = 70 X 50 = 3500
= 105 X 50 = 5250
Now the question is -4500/7500, -4500/7500, -3500/7500, -5250/7500
Now just arrange all this numbers in ascending numbers. Sorry but after typing this long answer I am very tried and can't type anymore!
