What Divided by 10 Equals 7?
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 10, equals 7?
Solving What Divided by 10 Equals 7
Here’s how you would set up this question as an equation:
x
10
=
7
\frac{x}{10} = 7
10 x = 7
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 10, resulting in this equation:
x
=
7
∗
10
x = 7*10
x = 7 ∗ 10
Then we simplify and find our answer:
x
=
70
x = 70
x = 70
So, the answer to the question “What divided by 10 equals 7?” is 70.To prove this, we can take the original problem:
x
10
=
7
\frac{x}{10} = 7
10 x = 7
And insert 70 in the place of x:
70
10
=
7
\frac{70}{10} = 7
10 70 = 7
Because this is true, the answer must be correct.
