Answer:

To find the value of x in the proportion 7:x = 21:24, you can set up a proportion equation and solve for x.

The proportion can be written as:

7 / x = 21 / 24

To solve for x, cross-multiply:

7 * 24 = 21 * x

Now, calculate the products on both sides:

168 = 21x

To isolate x, divide both sides by 21:

x = 168 / 21

Now, simplify the right side:

x = 8

So, the value of x is 8.
