To solve the problem:

1. Understanding the Problem:
   • Monique has 135 packages to ship.
   • Each crate can hold 5 packages.
   • We need to find out how many crates are needed.
2. Equation Setup: The total number of crates, $xx$x, can be found by dividing the total packages by the number of packages per crate:

   $x=\frac{135}{\mathrm{5<span></span>}}$

3. Solve the Equation: Perform the division:

   $x=135÷5=27$

4. Answer: Monique will need 27 crates to ship all the packages.
