6is less than a number is greater than 4

You have to translate the math word problem to math. 
"number" is any variable, so lets use x 
"6 less" is -6
"greater than" is > 
"4" is obviously 4

x-6>4 

if you need to solve for x as well, you would need to get it by itself. so add 6 to both sides(we are trying to get rid of 6 on the side with the x, so to get -6 to zero we had 6, and one thing we do on one side you do on the other). 

6 + 4= 10

so x=10

Using the rise/run rule. you would get 2/6.simp. 1/3
