To solve this inequality, we need to simplify the expression on the left side first.

75/45 - 18/36 can be simplified as follows:

75/45 = 5/3 (divide both numerator and denominator by 15)
18/36 = 1/2 (divide both numerator and denominator by 18)

Now we can rewrite the inequality as:

5/3 - 1/2 ≤ ?

To compare these fractions, we need to find a common denominator, which is 6. So we have:

(5/3) * (2/2) - (1/2) * (3/3) ≤ ?

10/6 - 3/6 ≤ ?

Now we can subtract the fractions:

(10 - 3) / 6 ≤ ?

7/6 ≤ ?

Since 7/6 is greater than 1, the inequality is not true. Therefore, the solution to the inequality is false.
