Final answer:
To find a percentage of a number, use the formula: (percentage/100) * number. To find what percent a number is of another number, use the formula: (number1/number2) * 100.
Step-by-step explanation:
To find 55% of a number, we can use the formula: 55% * x = 33. We need to solve for x. We can do this by dividing both sides of the equation by 55%. This simplifies to: x = 33 / 0.55 = 60. Therefore, 55% of 60 is equal to 33.
To find what percent 36 is of 80, we can use the formula: (36 / 80) * 100. The division gives us the decimal value of the fraction, and multiplying by 100 converts it to a percentage. So, (36 / 80) * 100 = 0.45 * 100 = 45%. Therefore, 36 is 45% of 80.
