3.2/0.2 = x/6.4
Cross multiply and solve for x.
3.2/0.2 = x/6.4
0.2x = 20.48
x = 20.48 / 0.2
x = ?
Using proportions and cross multiplication--
0.2x=(3.2)(6.4)
Therefore x= [(3.2)(6.4)]/.2
Thus, x= 102.4
To solve this equation for x, we can use cross-multiplication. Cross-multiplication is a method used for solving proportions.
First, let's set up the equation:
3.2/0.2 = x/6.4
In cross-multiplication, we multiply the numerator of the first fraction by the denominator of the second fraction and set it equal to the product of the denominator of the first fraction and the numerator of the second fraction.
So, we have:
(3.2)(6.4) = (0.2)(x)
Now, we can solve for x by simplifying the equation:
20.48 = 0.2x
To isolate x, we divide both sides of the equation by 0.2:
20.48 / 0.2 = x
This gives us:
x = 102.4
Therefore, the value of x that satisfies the equation 3.2/0.2 = x/6.4 is 102.4.
