Because they are equivalent ratios
100/1000 = 1/10 by dividing the numerator and denominator by 100
Divide by 10. There are 1000 grams in a kilogram, so you are dividing the numerator by 1000. There are 100 cm in a meter, so you are dividing the denominator by 100. 1000/100 is 10, so just divide the value in g/cm by 10 to get it's value in kg/m
John likes 1100. 900. He likes 400 but not 300; 400 is the square of an integer (20) but 300 is not. He likes 100 but not 99; 100 is the square of an integer (10) but 99 is not. He likes 3600 but not 3700; 3600 is the square of an integer (60) but 3700 is not. 900 is the square of an integer (30), but 1000, 1100, and 1200 are not.
3600 as a percentage = 360000% 3600 * 100% = 360000%
3600
36 percent of 3600 = 1296 36% of 3600 = 36% * 3600 = 36%/100% * 3600 = 0.36 * 3600 = 1296
There are 100 centimetres in one metre. Therefore, 3600 centimetres is equal to 3600/100 = 36 metres.
3600/100*5=180
3.5%/100% * 3600 = 126
There are 1000 meters in a kilometer(1000 m) / (1 km). There are 3600 seconds in an hour, so (1 hr) / (3600 s). you can just multiply (1 km / hr)*[(1000 m) / (1 km)]*[(1 hr) / (3600 s)] to get 0.28 m/s.
1000/10 = 100
First find 10% by dividing by 10. This gives 360. Then multiply by 2 to find 20%. 360 x 2 = 720 * * * * * True. But, in general, it is far simpler to mutiply 3600 by 20 and divide by 100 (or divide 3600 by 100 and then multiply by 20) Thus 3600/100 = 36 and 36*20 = 720. The above method is fine for 20% but try it with 13%. You find 10%. Then what? Take a tenth of the 10% to get 1% and then treble it to get 3%. Finally calculate 10%+3*1%. Possible, but plentry of room for error. Instead, all you need is 3600/100 = 36 and then 36*13 = 468!
