Hi can someone help me on this please? I am having trouble understanding this one :) thx

I would say its the bottom one

Step-by-step explanation:

The top one goes to five while the bottom only goes to four, plus you cant have a negative amount of people you can only have from 0 to infinity amount of people.

It's the second line

Because people can only be counted from zero.

the difference between a number and 5 is -2.

step-by-step explanation:

the difference between a number and 5 is -2.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
