Question

20% of a number is 30, what is the number?

Answer 1

To find the number when 20% of it is equal to 30, we can set up the following equation:

0.20x = 30

Here, "x" represents the unknown number we want to find. To solve for "x," we divide both sides of the equation by 0.20:

x = 30 / 0.20

x = 150

Therefore, the number is 150.

Answer 2

To find the number, we need to use algebraic equations. Let's assume that the number is "x." 

According to the problem, "20% of a number is 30." So, we can write it as:

0.2x = 30 

Now, we can solve for x by isolating it on one side of the equation. 

0.2x = 30 

Dividing both sides by 0.2: 

x = 150 

Therefore, the number is 150.

Answer 3

The number is 150.

To get this answer, we can use the fact that "20% of a number" is the same as "0.2 times the number". So we can set up the equation:

0.2x = 30

where x is the unknown number. To solve for x, we can divide both sides by 0.2:

x = 30 ÷ 0.2 = 150

Answer 4

20 percent of a number is 30 it means that 30 is actually the 1/5 of the number so 1/5of number =30 so cross multiple then the number will be 150

Answer 5

Let x be the number that we are going to find and given that 20% of x is equal to 30, which means 20% (x) = 30

Then (20×0.01)x = 30

           0.2x = 30

 Now dividing both side by 0.2 we get x= 30/0.2

Thus x = 150.

Hence,the number which its 20% is equal to 30 is exactly 150.

Answer 6

Let the number be X then you write

20/100 × X = 30

Multiply 20 & X you will have 

20X/100 = 30/1 [Cross multiply]

20X × 1 = 30 × 100 

20X = 3000

Make X subject formula

X = 3000/20

X = 150

Answer 7

To find the number, you can set up the equation:  20% of x = 30 

To solve for x, divide both sides of the equation by 0.2 (which is the decimal equivalent of 20%):

  x = 30 / 0.2  x = 150 

Therefore, the number is 150.
