Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. Use the following data to calculate the MAPD of the forecasts.

Keep two decimal places in your calculations.

Calculate the mean absolute percentage deviation (MAPD) of the forecasts?
