Q:

What Divided by 30 Equals 3?

Accepted Solution

A:
What Divided by 30 Equals 3? 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 30, equals 3? Solving What Divided by 30 Equals 3 Here’s how you would set up this question as an equation: x 30 = 3 \frac{x}{30} = 3 30 x ​ = 3 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 30, resulting in this equation: x = 3 ∗ 30 x = 3*30 x = 3 ∗ 30 Then we simplify and find our answer: x = 90 x = 90 x = 90 So, the answer to the question “What divided by 30 equals 3?” is 90.To prove this, we can take the original problem: x 30 = 3 \frac{x}{30} = 3 30 x ​ = 3 And insert 90 in the place of x: 90 30 = 3 \frac{90}{30} = 3 30 90 ​ = 3 Because this is true, the answer must be correct.
