    I came up with .0027 but I do not think that is right

    it says "in 2000, in Country A, the average networth of a family was $240,000 " so the question is asking what's already given...something seems off

    I typed it as it was written, I have to use scientific notation and round to the nearest tenth as needed \[\frac{ 2.4*10^{5} }{ ?8.8*10^{7} }\]

    i see how you got 0.0027, but the problem doesn't make sense. It gives you the net worth, but asks you what the net worth is.

    Then I came up with \[2.7\times10^{-2}\]

    \[\frac{ 2.4*10^{5} }{ 8.8*10^{7} } = \frac{2.4}{8.8} \times 10^{5-7}\] \[\frac{ 2.4*10^{5} }{ 8.8*10^{7} } = 0.27 \times 10^{-2}\] \[\frac{ 2.4*10^{5} }{ 8.8*10^{7} } = (2.7 \times 10^{-1}) \times 10^{-2}\] \[\frac{ 2.4*10^{5} }{ 8.8*10^{7} } = 2.7 \times 10^{-1-2}\] \[\frac{ 2.4*10^{5} }{ 8.8*10^{7} } = 2.7 \times 10^{-3}\]

    but I doubt that's what you're looking for since they want the net worth

    I am not sure where you came up with the 2.7 x \[10^{-1-2}\] because my examples from other problems just subtract straight down

    I'm adding the exponents because I'm multiplying 10^(-1) and 10^(-2)

    No I get that part, what I do not get is where the \[10^{-1}\] even came from????

    divide the parts seperately it equals \[2.7\times10^{-2}\]

    the answer is 0.0027, which in scientific notation is 2.7 x 10^(-3)

    maybe it is asking for the total networth of all the families combined.?

    I see the confusion. The problem is worded funny. It is your choice, finding the total seems more logical to me. As we are told in engineering, if you state your assumption you can not be wrong, haha. So state I am assuming they are asking for the total networth of all families. haha

    Is it maybe asking that i use the scientific notation of simplifying the $240,000 down to 2.4 x \[10^{5}\]

    Thank you to you both, I'm simply going to show the work and then explain where the word problem became confusing as to what it was asking for.

    That is the entire problem. and then it says Country A's total family net worth is ____ dollars? (use scientific notation, and round to the nearest tenth as needed
