Question

Does anyone know this

Answer 1

Hey!


The first step to solving this would be to cross multiply the fractions. So, when you set up your equation it would look something like the...

Original equation :

`(8)/(x) = (20)/(10)`

New Equation {Apply Fraction Cross Multiplication} :
8 · 10 = x · 20

Now we switch the sides of the equation to get the variable x on the left side, which is generally where we always want x.

Old Equation :
8 · 10 = x · 20

New Equation {Switched} :
x · 20 = 8 · 10

Now we'll multiply the numbers 8 and 10.

Old Equation :
x · 20 = 8 · 10

New Equation {Multiplyed Left Side of the Equation} :
x · 20 = 80

Next we'll divide both sides by 20 to get x on its own.

Old Equation :
x · 20 = 80

New Equation {Added Divide Both Sides} :

`(x*20)/(20) = (80)/(20)`

Now we'll solve the equation.

Old Equation :

`(x*20)/(20) = (80)/(20)`

Solution {Old Equation Solved} :
x = 4

So, this means that in the equation provided x = 4.

Hope this helps!
