Answer:

Step-by-step explanation:
To divide fractions, here are your steps:
1) Invert the fraction you are dividing by.
2) Multiply the numerators and denominators.
3) Simplify if necessary.
1)
/ 
2)
= 
3)
Cannot be further simplified.
So we need to find the inequality, Simple!
So we only have 5 dollars. That we cannot change.
But the snadwich, however, we can change how much we buy. But this problem is asking us how many we can buy. So that is an x. So far, we have 2.25x.
Then we have to use the inequality sign 'less than or equal to' because we can buy less or equal to 5 dollars.
So the equation is

Then we solve by isolating the x. We divide 2.25 both sides then we get
