find each missing number.

1.)19/n = 0.76
2.)n:20 = 0.55
3.)n = 1:10 (n is a decimal)
4.) n% = 1:100
5.) n% = 33:100
6.) 99% (n is a decimal)
7.) n/25 = 17:25
8.) 41:n = 0.82
9.) n/25 = 0.08
10.) 21:n = 0.21

1.)

19 / n = 0.76 Multiply both sides by n

19 = n * 0.76 Divide both sides by 0.76

19 / 0.76 = n

25 = n

n = 25

2.)

n : 20 = 0.55 Multiply both sides by 20

n = 0.55 * 20

n = 11

3.)

n = 1 : 10

n = 0.1

4.)

n % = 1 : 100

1 % = 1 : 100

5.)

n % = 33 : 100

33 % = 33 : 100

6.)

99 % = 99 : 100 = 0.99

7. )

n / 25 = 17 : 25

Obviously n = 17

8. )

41 : n = 0.82 Multiply both sides by n

41 = n * 0.82 Divide both sides by 0.82

41 / 0.82 = n

50 = n

n = 50

9. )

n / 25 = 0.08 Multiply both sides by 25

n = 25 * 0.08

n = 2

10. )

21 : n = 0.21

Obviously n = 100 becouse

21 : 100 = 0.21

To find the missing number in each of the given equations, we need to isolate the variable on one side of the equation. Let's go through each equation step by step:

1.) 19/n = 0.76

To isolate the variable "n", we can multiply both sides of the equation by "n". This gives us:

19 = 0.76n

Now, we can divide both sides of the equation by 0.76 to find the value of "n":

n = 19/0.76

Calculating the value, we get:

n ≈ 25

So, the missing number is approximately 25.

2.) n:20 = 0.55

To isolate "n", we can multiply both sides of the equation by 20:

n = 0.55 * 20

Calculating the value, we get:

n = 11

So, the missing number is 11.

3.) n = 1:10 (n is a decimal)

It seems there might be a missing operator or symbol in this equation. If "n" is a decimal, it should be written with a decimal point. Please clarify the equation.

4.) n% = 1:100

To find the missing number, we can convert the percentage to a decimal. "1%" is equivalent to 0.01. So, the equation becomes:

n = 0.01 * 100

Calculating the value, we get:

n = 1

So, the missing number is 1.

5.) n% = 33:100

Similar to the previous equation, we can convert "33%" to a decimal. "33%" is equal to 0.33 as a decimal. The equation becomes:

n = 0.33 * 100

Calculating the value, we get:

n = 33

So, the missing number is 33.

6.) 99% (n is a decimal)

It seems there might be a missing equation associated with this statement. Please provide more information or clarify the missing number you are referring to.

7.) n/25 = 17:25

To isolate "n", we can multiply both sides of the equation by 25:

n = 17 * 25

Calculating the value, we get:

n = 425

So, the missing number is 425.

8.) 41:n = 0.82

To isolate "n", we can divide both sides of the equation by 0.82:

n = 41 / 0.82

Calculating the value, we get:

n ≈ 50

So, the missing number is approximately 50.

9.) n/25 = 0.08

To find the missing number, we can multiply both sides of the equation by 25:

n = 0.08 * 25

Calculating the value, we get:

n = 2

So, the missing number is 2.

10.) 21:n = 0.21

To isolate "n", we can divide both sides of the equation by 0.21:

n = 21 / 0.21

Calculating the value, we get:

n = 100

So, the missing number is 100.
