Melani is 172.3 centimeters tall. If she were 10.5 centimeters taller, she would be twice as tall as her younger brother Daniel.
How tall is Daniel?
noob
Starting height: 172.3
172.3 + 10.5 = 182.8cm
Ending height: 182.8cm

Now divide that by two to get Daniels height:
182.8/2 = 91.4

Therefore, Daniel is 91.4cm tall.
