If spot eats 156 pounds of food each year and he eats the same amount each month, how much does he eat in 1 month?

One year is 12 months and you want to know how much Spot eats in one month. So your going to divide 156 by 12 to get the amount of food eaten in one month.

156/12= 13 pounds

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
