Another step by step method

Step 1: Let's solve the equation for Y by first rewriting it as: 100% / 27 = 90% / Y

Step 2: Drop the percentage marks to simplify your calculations: 100 / 27 = 90 / Y

Step 3: Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 27 ) = 90

Step 4: To isolate Y, multiply both sides by 27 / 100, we will have: Y = 90 ( 27 / 100 )

Step 5: Computing the right side, we get: Y = 24.3

This leaves us with our final answer: 90% of 27 is 24.3
