81 is 18% of what number?


Enter your answer in the box.

Answers

Answer 1

Answer:

450

Step-by-step explanation:

Formula = Number x 100

Percent = 81 x 100

18 = 450

Following shows the steps on how to derive this formula

Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.

81

18% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

18Y = 81 x 100

18Y = 8100

Y = 8100

100 = 450

Answer 2

Answer:

450

Step-by-step explanation:

18% of 450 is 81. 100% of 450 is 450, therefore 18 percent of 450 equals 81. To learn how to solve 81 is 18 percent of what Number, see the step by step instructions below.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of paint are needed for one door? Consider drawing a model to help you solve the problem.

Answers

Answer:

1 and 1/4 liters of paint are needed for one door

Step-by-step explanation:

You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 and 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.

Hope this helps!

1.25 liters! if 2 liters is for 1 3/5 door, you will divide 2 and 1 3/5 to get 1.25 per door!
