I dont know how to convert the number 148.3 to binary form.

2. Relevant equations

Just having a decimal point really throws in a monkey wrench in the "keep dividing by and if a number halfed has a decimal point ignore the after decimal point stuff two" procedure.

3. The attempt at a solution

I got the answer 101010001 but I looked the answer up and it's apparently 10010100.How can this be?.I was desperate enough to just look up the answers but I still dont how 200.45 can be 11001000,100.9 can be 1100100 and 9001.375 can be 10001100101001

If it helps me teacher wrote a note that looks like this ...
