Answer 1

Answer:

Step-by-step explanation:

3/4 ; 3/5 ; 5/6

Step 1: Find LCM of denominators

LCM of 4,5,6 = 2x2x5x3

                     = 60

Step 2: Change denominators to 60 and multiply numerators by the same no. you used to multiply the denominators to 60.

3/4 = 3x15/4x15 = 45/60

3/5 = 3x12/5x12 = 36/60

5/6 = 5x10/6x10 = 50/60

Step 3: Line them up

45/60 ; 36/60 ; 50/60

Step 4: Compare and arrange them

36/60 < 45/60 < 50/60

3/5 < 3/4 < 5/6
