Step 2:: Define the problem
Let's set up an equation where $$x$$ represents the unknown total number, and we know that 90 is 40% of this number.
Step 3:: Convert the percentage to a decimal
0.40x = 90
Step 4:: Solve for x by dividing both sides by 0.40
x = \frac{90}{0.40}
Step 5:: Calculate the result
x = 90 \div 0.40 = 225
Step 6:: Verify the solution
Let's check: $$0.40 \times 225 = 90$$ ✓
Final Answer
90 is 40% of 225.
