8/30=x/75
solve for x
Cross multiply and you get 30x=600. 600/30 will give you your answer.
divide top and bottom of left by 2
4/15 = x/75
multiply both sides by 5
4/3 = x/15
then multiply both sides by 3
4 =x/5
now that it is manageable, multiply both sides by 5
20 = x
To solve for x in the equation 8/30 = x/75, you can cross-multiply and then divide by the denominator on the other side. Here's the step-by-step solution:
Step 1: Cross-multiply
8 * 75 = 30 * x
Step 2: Simplify
600 = 30x
Step 3: Divide both sides by 30
600/30 = x
20 = x
Therefore, x = 20.
