Q:

What Divided by 81 Equals 6?

Accepted Solution

A:
What Divided by 81 Equals 6? Methods Setting up the problem: In a problem like this, the “what” means that we’re working with a variable. The most common variable used in math is “x”. So, we could say what number, x, when divided by 81, equals 6? Solving What Divided by 81 Equals 6 Here’s how you would set up this question as an equation: x 81 = 6 \frac{x}{81} = 6 81 x ​ = 6 The goal of the problem is to solve for x. To do this we need to change the equation so that x is alone on one side of the equation.In this case, we can do that by multiplying both sides of the equation by 81, resulting in this equation: x = 6 ∗ 81 x = 6*81 x = 6 ∗ 81 Then we simplify and find our answer: x = 486 x = 486 x = 486 So, the answer to the question “What divided by 81 equals 6?” is 486.To prove this, we can take the original problem: x 81 = 6 \frac{x}{81} = 6 81 x ​ = 6 And insert 486 in the place of x: 486 81 = 6 \frac{486}{81} = 6 81 486 ​ = 6 Because this is true, the answer must be correct.
