Use the table to determine the location with the greatest amount of rainfall and the location with the least amount of rainfall. Location Amount of Rainfall 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 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. Describe what this ratio tells you.

Is this a question you need help on or are you asking the people on here to write what they think?

silvernight269:

@hannieee

hannieee:

I need help with answering the question

hannieee:

I'm not sure where to start

silvernight269:

Ok got it

silvernight269:

Ok so Im guessing you already know which numbers to pick for the greatest and for the smallest?

hannieee:

Hawai'i has the most, death valley has the least

hannieee:

isn't it best to convert all to mm?

silvernight269:

No. You can convert meters to centimeters.

hannieee:

aha okay

silvernight269:

Or cm to m

silvernight269:

But since the question is wanting as a whole number its better to convert m to cm

hannieee:

okay. that makes sense

silvernight269:

Yea

silvernight269:

Do you know the converted number?

hannieee:

no I don't

hannieee:

i know them in mm

silvernight269:

Well first go ahead and convert the 0.1173 m into mm

hannieee:

117.3mm

hannieee:

i have a list of all of them if that's better

hannieee:

117.3mm 11400mm 256mm 57mm 160mm 4800mm

hannieee:

there

silvernight269:

Ok great! now to convert mm to cm. What do you need to do

hannieee:

11.37cm 1140cm 25.6cm 5.7cm 16cm 480cm

silvernight269:

Great! Now if you put the greatest and the least as a ratio, it would look like 480 : 11.37

hannieee:

but those two are not the greatest and the least

silvernight269:

lmao oops sorry my bad

hannieee:

haha np

silvernight269:

Was looking at the wrong numbers XD

hannieee:

no problem! haha!

silvernight269:

So the correct ratio would be 1140 : 5.7

silvernight269:

And since the problem wants us the have the ratios as whole numbers, what do you think we should do?

hannieee:

I'm not sure

silvernight269:

Well, what we can do first is divide the greatest by the least so that we can put in the ratio, a 1 in the least

hannieee:

I don't understand what you mean

silvernight269:

\[1140\div5.7\]

hannieee:

200

silvernight269:

Yes thats right! now since we could divide 1140 cm by 5.7 cm to equal a whole number of 200 that just means Hawai'i's amount of rainfall is 200x larger than the amount of rainfall death valley has.

hannieee:

aha okay I think I get it.

silvernight269:

Yep!

hannieee:

So that answers what the ratio tells us right?

silvernight269:

Yes. All you need to do now is just write and explain in full complete sentences lol

hannieee:

Right! Thank you so so much!!

silvernight269:

No problem! Sorry if I made you confused at some parts. Have a nice day!

hannieee:

No not at all! You explained it very well! Have a nice day as well!
