3/5 or 0.6
It is 3/5 because you can divide by 10 on the top and bottom. 30/50=3/5
Find the conman denominator for 30/50. What goes into both of them? What times what equals 30, and when you find that out then it'll work with 50 too. If it doesn't then it can't be reduced anymore. Try to figure it out, I know you can. Albert Einstein figured out a whole formula by himself, so trust me you can figure this out.
54 kilometers per hour
according to rules:
1 km = 1000 meter
which means that 1 meter = 1/1000 km
1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]
which means that 1 second = 1/3600 hour
therefore, 1 kilometer/hour =
thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.
15 meter/second= which is the required answer.
30/50 in simplest form....
