Question

A teachers desk is 5.5 meters long a students desk is 220 centimeters long what is the difference in the length in centimeters between a teachers desk any students desk

Answer 1

so if 5.5 is in meter let change it to cm because the question want us to give the answer in cm.

`1cm = 0.01meter`

`to \: turn \: meters \: into \: \\ cm \: we \: have \: to \: multiply \: by \: 100`

now we multiply 5.5 times 100 which is equal to 550.

next we subtract 550 - 220= 330.

finally, the difference between a teacher and student is 330cm .meaning the teacher's desk is 330 cm longer or taller than the student.
