Use the table to determine the location with the greatest amount of rainfall and the location with the least amount of rainfall. a.Using complete sentences, identify the location with the greatest amount of rainfall and the location with the least amount of rainfall, and express the ratio of their respective rainfalls as a whole number. b. Describe what this ratio tells you. Needles, California 0.1173 m Mt. Waialeale, Hawai'i 11.4 m Puako, Hawai’i 25.6 cm Death Valley, California 57 mm Mojave, California 160 mm Hilo, Hawai'i 480 cm

    Can you upload a image for the question instead...you should pay attention to the units, know that meters (m) > centimetres (cm) > millimetres (mm)

    So if you notice Mt. Waialeale, Hawaii it says 11.4m and assuming that is for greatest amount of rainfall that would be it. Do you get the idea?

    We should convert them all to a certain unit, so maybe meters, or what ever you're most comfortable with. So you can get a clearer picture. \[1m = 100 cm = 1000 mm\]

    I think it's important you understand that first and we can move on then, we will have to convert the others to meters, so let me know whenever you're ready.

    That's right but wait a second, because notice that's in cm, not meters. We have to convert it to m first before we put it in scientific notation.

    Anything to the power of 0 is 1, so 4.8 x 10^0 = 4.8 since 10^0 = 1, I know it seems a bit silly, but that's how it works haha.

    Np, but it says it wants a whole number right? So that means it has to be something like 1, 2, 3 etc...so we should get 11.4/0.057 = 200 (whole number) meaning the amount of rainfall in Mt. Walaleale is 200x more than in Death Valley, and makes sense, Death Valley is a very dry place if I recall right :P (name even says so!).
