) Solve the proportion x/8=30/40
To solve the proportion x/8 = 30/40, we need to cross-multiply and then solve for x.
Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa.
(x * 40) = (8 * 30)
40x = 240
Now, divide both sides of the equation by 40 to isolate x:
40x/40 = 240/40
x = 6
Therefore, the solution to the proportion x/8 = 30/40 is x = 6.
