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.
