153-27-19= 107 Hector serves 107 ice cream cones on the weekdays. All you do is subtract the 2 weekend days from the total and you get the answer of the ice cream cones on the other 5 weekdays. *If needed-- He would have sold about 21 cones each WEEKDAY*
Because for dividing one positive and one negative number, the rule is that the answer is going to be negative. So, what you can do is just do 56÷8 which equals 7 then add the negative sign to make it -7.
