Answer 2

To find the value of 'x' in the equation 6:7 = 18:x, we can set up a proportion.

The ratio 6:7 is equivalent to the fraction 6/7. We can set up the proportion:

6/7 = 18/x

To solve for 'x', we can cross-multiply:

6x = 7 * 18

Multiply 7 by 18:

6x = 126

Now, divide both sides of the equation by 6 to isolate 'x':

x = 126 / 6

Performing the division:

x = 21

Therefore, in the equation 6:7 = 18:x, the value of 'x' is 21.
