Make them similar fractions.
For no. 1:
Their LCD is 20, therefore, the fractions will become... 4/5 = 16/20; 2/4 = 10/20; 3/5 = 12/20; 3/4 = 15/20
10/20, 12/20, 15/20, 16/20 ... so the answer (increasing order) will be 2/4, 3/5, 3/4, 4/5.
For no. 2:
Their LCD is 6, therefore, the fractions having "6" as the denominator remains the same while the 1/2 will become 3/6 and the 2/3 will become 4/6. 2/6, 3/6, 4/6, 5/6 ... so the answer (increasing order) will be 2/6, 1/2, 2/3, 5/6
For no. 3:
Their LCD is 30, therefore, the fractions will become... 2/5 = 12/30; 5/6 = 25/30; 10/15 = 20/30 so....
12/30, 20/30, 25/30 that will become 2/5, 10/15, 5/6
For no. 4:
Their LCD is 60. So... the fractions will become 9/20 = 27/60; 4/10 = 24/60; 3/15 = 12/60; 4/5 = 48/60... so... 12/60, 24/60, 27/60, 48/60... 3/15, 4/10, 9/20. 4/5
