Division of Rational Numbers

To solve this problem, we need to determine the rate of change of the temperature of molten copper and then use that rate to find the change in temperature over a different time period.

Given: - The temperature of molten copper changed by "-40" degrees in 20 minutes.

We need to find: - The change in temperature of molten copper in 4 minutes.

To find the rate of change of the temperature, we can divide the change in temperature by the time taken. In this case, the rate of change is -40 degrees/20 minutes.

To find the change in temperature in 4 minutes, we can multiply the rate of change by the new time period. In this case, the change in temperature is (-40 degrees/20 minutes) * 4 minutes.

Let's calculate the change in temperature:

(-40 degrees/20 minutes) * 4 minutes = -8 degrees

Therefore, the temperature of molten copper will change by -8 degrees in 4 minutes.

Please note that the above calculation assumes a constant rate of change of temperature over time.
