If 18 is 45% of a value, what is that value?

7 answers

We can use the proportionality formula to find out the value:

18/x = 45/100

Where x is the value we are looking for.

To solve for x, we can cross-multiply to get:

18 x 100 = 45 x x

1800 = 45x

Dividing both sides by 45 gives:

x = 40

Therefore, the value is 40.
If 75 is 25% of a value, what is that value?
We can use the proportionality formula to find out the value:

75/x = 25/100

Where x is the value we are looking for.

To solve for x, we can cross-multiply to get:

75 x 100 = 25 x x

7500 = 25x

Dividing both sides by 25 gives:

x = 300

Therefore, the value is 300.
An economy package of cups has 440 green cups. If the green cups are 20% of the total package, how many cups are in the package?
We can use the proportionality formula to determine the number of cups in the package:

440/x = 20/100

Where x is the total number of cups in the package.

To solve for x, we can cross-multiply to get:

440 x 100 = 20 x x

44000 = 20x

Dividing both sides by 20 gives:

x = 2200

Therefore, there are 2200 cups in the package.
If 12 is 10% of a value, what is that value?
We can use the proportionality formula to determine the value:

12/x = 10/100

Where x is the value we are trying to find.

To solve for x, we can cross-multiply to get:

12 x 100 = 10 x x

1200 = 10x

Dividing both sides by 10 gives:

x = 120

Therefore, the value is 120.
