Least common multiplue is the smallest number that the 2 numbers can multiply into so exg LCM of 3 and 2 is 6,
to find, find the factors
12=2 times 2 times 3
18=2 timeds 3 times 3
so combine all of them
in 12, we have 2 2's and 1 three
in 18, we have 1 2 and 2 3's so
we must have 2 2's and 2 3's so
2 times 2 times 3 times 3=36=lcm\
so find factors and group
lcm=36
Answer:
Step-by-step explanation:
Answer:
The speed is:
5 meters per second
In then seconds: 50 meters
Step-by-step explanation:
1 hour = 3600 seconds
1 km = 1000 meters
18km = 18*1000 = 18000 meters
then:
18km/h = 18000m/3600sec = 5m/s
The speed is:
5 meters per second
proportions:
5 meters ⇔ 1 second
W meters ⇔ 10 seconds
W = 5*10/1
W = 50 meters
