Alright. Let me help you understand this better.
Usually, there is an amount that equals to the other.
Ask ourselves, how many cm in a meter?
1 meter = 100 centimeters
Now, how many centimeters do we have here?
234
Ok, see how many meters are in that.
234 = 2.34 centimeters.
This is another way to solve this.
Since 1:100 is our ratio, we can solve for a proportional relationship.
1/100 = x/234
Cross multiply
1*234 = 234
100*x = 100
234/100 = ?
234/100 = 2.34
There we go! Same answer! :D
Final answer: 2.34 meters
