write each ratio in simplest form.200 cm:8 km?

1 kilometer = 100 000 centimeters\n\nso we have\n\n200: 100000\nor\n1:500

Just "m" (always lower case)\n\n1 km = 1000 m

I like using the phrase, "Kangaroos Hop Down University Drive Collecting Money" to remember the terms for kilo, hecto, deca, unit, deci, centi, and milli.  Once you have this down, you can write down the letters K, H, D, U, D, C, M to figure out how to move the decimal.  For example, if you are going from kilograms to decigrams, you would go from K to the second D which is 4 spots to the right, so you would move the decimal four places to the right.  So, 4 kilograms is 40000 decigrams and 60 centimeters is 0.6 meters (two places to the left from M to U).

About 3.1 miles, but you can look this up easily in Google. Just type "5 km in miles".  You can do all sorts of conversions this way.

1 km=.62mile\nso 3650~2265

you go on google, find out the meter length of a beverage can\nmultiply that by 1 billion (1 X 10^9 i believe) and divide by 1000 (giving you km)

1 km = 100,000 cm\n2500 km = 2,500,000 cm\nI'm not sure if your scale is supposed to be 1:10,000,000 or 1:100,000,000, but the answer is either .25 cm (2,500,000/10,000,00) or .025 cm (2,500,000/100,000,000) depending.

kilometer. one kilometer = about 0.62 mile

H = 0.8 x (200 - A)\n68 = 0.8 x (200 - A)  {{Replace H with 68}}\n68/0.8 = 200 - A  {{Divide by 0.8}}\n85 + A = 200  {{Add A}}\nA = 200 - 85  {{Subtract 85}}\nA = 115\n\nWhatever you do to one side, you have to do the other.\nHope that helped!\n~Ruj x

230*10^-5N  a very small amount. formula is Gm1m2/d^2. convert distance in mts. \n    6.67*10^-11 * 70 * 7.35*10^22 / (3.86 * 10^8)^2\n\n    6.67*70*7.35 * 10^-5 /3.86 * 3.86\n    \n     230.322 * 10^-5

If you are drawing a blue print of a house, you might want to make one centimeter (100th of a meter) on you paper equal one meter of the actual house.  So if you wanted to draw a room 8 meters long, You would draw only 8 centimeters on your paper.  In other words:\n\n1/100=x/800\n\nMultiply both sides by 800 to isolate x, and you get 8 centimeters.
