Answer 1

Ответ:

х = 12

Пошаговое объяснение:

3 : 5 = х : 20

5х = 20*3

5х = 60

х = 60/5

х = 12

Answer 2

Solving for the Value of x in the Equation 3/5 = x/20

To solve for the value of x in the equation 3/5 = x/20, we can use cross multiplication to find the value of x.

Cross Multiplication: Cross multiplication is a method used to solve for an unknown variable in a proportion. It involves multiplying the numerator of one ratio by the denominator of the other ratio and setting the two products equal to each other.

Solution Process

Using cross multiplication, we can solve for the value of x in the given equation:

Step 1: Cross Multiply - Cross multiply the terms in the equation 3/5 = x/20.

   3 * 20 = 5 * x
   

Step 2: Solve for x - Solve for x by dividing both sides by 5.

   60 = 5x
   x = 60 / 5
   x = 12
   

Conclusion

Therefore, the value of x that satisfies the equation 3/5 = x/20 is x = 12. This means that when x is equal to 12, the equation 3/5 = x/20 is true.
