Question

The humidity dropped an average of 1 1/3% each hour over the last six hours. What was the total change in humidity?

Answer 1

Answer: A . -8%

Step-by-step explanation:

Given : The humidity dropped an average of $1\dfrac{1}{3}\%$ each hour over the last six hours.

which can be written as  $-\dfrac{3+1}{3}\%=\dfrac{4}{3\%}$

Then , the total change in humidity in 6 hours will be:-

$-6\times\dfrac{4}{3\%}=-8\%$

Hence, the total change in humidity = -8%

Thus , option A is the correct option.

Answer 2

C: - 7 1/3 %
You have to take 11/3 * 6 which equals 22 then divide 22 by 3 and it equals 7 1/3 since its dropping in humidity its negative. <span />
