Q:
# 42 Divided by What Equals 70?

Accepted Solution

A:

42 Divided by What Equals 70?
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 42 by to equal 70?
Solving 42 Divided by What Equals 70
Here’s how you would set up this question as an equation:
42
x
=
70
\frac{42}{x} = 70
x 42 = 70
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 42:
42
=
70
∗
x
42 = 70*x
42 = 70 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 70:
42
70
=
x
\frac{42}{70} = x
70 42 = 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
=
0.600
x = 0.600
x = 0.600
