Percentage = (30 / 60) x 100
C. Step 3: Determine the values needed for the formula
In the formula, the part is the number you want to find the percentage of, and the whole is the total number. Make sure you have both values before doing the calculation.
D. Step 4: Do the calculation
Using the values from step 3, apply them to the formula and calculate the percentage.
E. Step 5: Convert the answer into a percentage
After calculating the percentage, convert the answer into a percentage format by adding the % sign.
