Final answer:
To write an equation with 20 as the product and 4 as a factor, you can use the equation x * 4 = 20. Solving for x gives x = 5.
Step-by-step explanation:
To write an equation with 20 as the product and 4 as a factor, you can use the multiplication operation. Let's represent the equation as x * 4 = 20. In this equation, x represents the other factor that, when multiplied by 4, gives a product of 20. To find the value of x, you can divide 20 by 4, which gives you x = 5.
