What Divided by 70 Equals 9?

Accepted Solution

A:
What Divided by 70 Equals 9? 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 70, equals 9? Solving What Divided by 70 Equals 9 Here’s how you would set up this question as an equation: x 70 = 9 \frac{x}{70} = 9 70 x ​ = 9 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 70, resulting in this equation: x = 9 ∗ 70 x = 9*70 x = 9 ∗ 70 Then we simplify and find our answer: x = 630 x = 630 x = 630 So, the answer to the question “What divided by 70 equals 9?” is 630.To prove this, we can take the original problem: x 70 = 9 \frac{x}{70} = 9 70 x ​ = 9 And insert 630 in the place of x: 630 70 = 9 \frac{630}{70} = 9 70 630 ​ = 9 Because this is true, the answer must be correct.
