53 Divided by What Equals 43?
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 can we divide 53 by to equal 43?
Solving 53 Divided by What Equals 43
Here’s how you would set up this question as an equation:
53
x
=
43
\frac{53}{x} = 43
x 53 = 43
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, it can be done in two steps. The first step is to multiply both sides by x to isolate 53:
53
=
43
∗
x
53 = 43*x
53 = 43 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 43:
53
43
=
x
\frac{53}{43} = x
43 53 = x
When we simplify the new equation, we can solve for x. In this example, we will round to the nearest three decimal places if that’s needed.
x
=
1.233
x = 1.233
x = 1.233
