Answer:
Yes it is.
Step-by-step explanation:
There are two ways to do this.
1: Find a common denominator, such as _/24. First, you do how many times does 6 go into 24? Well, 4, so then do 4x4 = 16/24 then do the same thing for 8. 8x3=24, so 2x3=6/24. So 16/24 is greater than 6/24.
2: 4/6 = 0.667 and 2/8 = 0.25. So yes, 0.667 is greater.
