No could be represented as N, Yes can be Y, and X can be neither. You have to first see how many people they asked in total. So add 1225, 498, and 395. You get 2118. So that would be the bottom number on all the fractions.
No would be 1225/2118
Yes would be 498/2118
Neither would be 395/2118
You have to be sure you'd put like N=1225/2118 and y=498/2118 and x=395/2118
So you only need to solve for yes. So the other information should have been included so you could get the total number of people who answered, aka "the bottom number"
so yes is 498/2118 and you have to represent it with a number, I chose y. But usually they like x if there is only one to solve for.
You need to reduce. With such a high number it can be tough. But I can see right way I can do 2.
498 divided by 2 is 249. 2118 divided by 2 is 1059.
That makes it y=249/1059
Both of those can reduce by 3. 249 divided by 3 is 83. 1059 divided by 3 is 353.
That makes y=83/353
That's the lowest it can go.
