Answer:

0.30 * 140 = x

Step-by-step explanation:

The equation that shows the relationship "30% of 140 is x" can be written as:  0.30 * 140 = x  To calculate this, you multiply 0.30 (which represents 30% as a decimal) by 140 (the given number). The result will be the value of x.  0.30 * 140 = 42  Therefore, x = 42. So, 30% of 140 is equal to 42.
