The reciprocal is equal to
Part b) we have
450
we know that
the given number can be expressed as 
so
changing the numerator and denominator
The reciprocal is equal to
is that a variable of x or a multiplication sign?
You know that anything times a one is that number, so multiply 2,3, and 4, and then multiply that by one. once you get the answer, put the zeros behind each multiplied number behind your answer, and there you go.
2×3×4= 24×1=24
there are 4 zeros
