In a community service class in the fall, 333 of the 151515 class sessions were lectures, while all others were devoted to fieldwork in parks. in the spring, the number of sessions devoted to fieldwork remained the same, but the total number of sessions increased to 181818. in the spring, what percent of class sessions were lectures?

16.85%

Step-by-step explanation:

First, we need to finde the percent of lectures and fieldwork during the fall.

Total classes: 151,515

# of lectures: 333

# of fieldwork: 151,515-333 = 151,182

Now, if total classes increases to 181,818 and the number of fieldwork remainded the same, we get:

# of lectures: 181,818 - 151,182 = 30,636

% of lectures: 30,636 / 181,818 = 0,1685 *100 = 16.85%
