74 Divided by What Equals 90?
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 74 by to equal 90?
Solving 74 Divided by What Equals 90
Here’s how you would set up this question as an equation:
74
x
=
90
\frac{74}{x} = 90
x 74 = 90
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 74:
74
=
90
∗
x
74 = 90*x
74 = 90 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 90:
74
90
=
x
\frac{74}{90} = x
90 74 = 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
=
0.822
x = 0.822
x = 0.822
