Math tutor helps solve: hat Divided by 45 Equals 30?

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 45, equals 30?

Math Tutor Helps Solve: What Divided by 45 Equals 30

Here’s how you would set up this question as an equation:

\frac{x}{45} = 30

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 45, resulting in this equation:

x = 30*45

Then we simplify and find our answer:

x = 1350

So, the answer to the question “What divided by 45 equals 30?” is 1350.To prove this, we can take the original problem:

\frac{x}{45} = 30

And insert 1350 in the place of x:

\frac{1350}{45} = 30

Because this is true, the answer must be correct.
