Use mental math to determine the solution to start fraction x over 3 end fraction = 24.

To determine the value of x in the equation (x/3) = 24, we can use mental math.

First, since we have the fraction (x/3), we can imagine multiplying both sides of the equation by 3 to cancel out the denominator. This gives us x = 24 * 3.

Next, multiplying 24 by 3, we have:
24 * 3 = 72.

Therefore, the solution to the equation (x/3) = 24 is x = 72.

To solve the equation x/3 = 24 mentally, you can follow these steps:

Step 1: Multiply both sides of the equation by 3 to isolate the variable x.
(x/3) * 3 = 24 * 3
This simplifies to x = 72.

Therefore, the solution to the equation x/3 = 24 is x = 72.
