The question simply requires one to get the sum of rainfall within the two months. Considering that the rainfall amount in July is given as 3.6 inches while for August is 4.7 inches then the sum will be 3.6+4.7= 8.3 inches. Note that during the addition of decimals, the numbers in the tenth part if added sum up to 0.7+0.6=1.3 then we write three, carry 1. Adding the carry over 1 to 3 and 4 we get 8. Therefore, the total rainfall in both months is 8.3 inches
