25 lightening strikes in June, 51 lightening strikes in July, 62 lightening strikes in august.

what is the average number of lightening strikes per day?

June has 30 days, July has 31, and August has 31.

92 days in total.

25 + 51 + 62 = 138 lightning stikes

138 / 92

1.5 lightning strikes per day on average.

So avarage is number of occurances over total or strikes/days

June=30 days

July=31 days

August=31 days

so total = 30+31+31=92

there were 62+25+51=# of lightnig strikes=138

so 138/92 or (2*3*23) / (2*2*23) or [ (2*23) / (2*23) ] times 3/2 so [ (2*23) / (2*23) ] cancels out to 1/1 or 1 and the answer is 3/2 lighning strikes per day or 1 1/2 per day
