Math tutor helps solve: hat Divided by 3 Equals 81?
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 3, equals 81?
Math Tutor Helps Solve: What Divided by 3 Equals 81
Here’s how you would set up this question as an equation:
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 3, resulting in this equation:
Then we simplify and find our answer:
So, the answer to the question “What divided by 3 equals 81?” is 243.To prove this, we can take the original problem:
And insert 243 in the place of x:
Because this is true, the answer must be correct.
