Answer:
8
Step-by-step explanation:
You just find the prime factors of each number in order to find the GCF.
You would start by subtracting 5-7=2 which would make the equation
3x=x-2 then subtract x from both sides to get 2x=-2 then you would divide both sides by -2 so x=1
Divide 14/18 then divide 16/20. 14 divided 18 is .777 while 16 divided by 20 is .80. Therefore Trey did better.
My common denominator is a 08 cause as I look at the fraction I have a1/2 also falod 1/4 which I had to take of the one to make a 0to subtract to the 2 to give it a 12 to be able to take from the four we have and that is how I came up with a common denominator of 08
Yes because 4/8 would be half so anything above 4/8 is more then half.
