Answer 3

Finding the Unknown Number

To find the unknown number in the given equation, we can set up an equation and solve for the unknown. The equation states that the sum of an unknown number and the quotient of two numbers, 90 and 5, is equal to 100.

Let's denote the unknown number as x. The equation can be written as:

x + (90 / 5) = 100

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting (90 / 5) from both sides of the equation:

x = 100 - (90 / 5)

Now, let's calculate the value of x:

x = 100 - (90 / 5) = 100 - 18 = 82

Therefore, the unknown number is 82.
