First divide 3 both side
Than move 4 to another side
Than divide by 2
Easy!
All you have to do is make a number lower or higher according to the symbols and make it unique.
For example, on letter B, it says ____ - ____ = <1
So what you want to do is make it 0 - 0 = <1
The answer is C
Because you have to add them all up. So add the 1/3 and 2/3 which equals 3/3 which is equal to 1. So then you add the 1/6 which equals 2/6 which is equivalent to 1/3 then you add that 1/3 to the last 1/3 which also equals 2/6 and as we established that equals 1/3 so the answer is 1 and 1/3.
