Extracting numerator and denominator values from a decimal value

I want matlab to automatically extract numerator and denominator values from a decimal value when I enter one.

For example, I entered a value R (Variable) = 6.52 , so matlab should automatically assign L (Numerator) = 652 and M (Denominator) = 100 .

Basically, I'm doing Resampling in Digital Signal Processing course, and whenever I enter the value of resampling factor, I want matlab to automatically extract Interpolation (L) and Decimation (M) factors from that value, for further processing (manual resampling).

[N,D] = rat(6.52)

N = 163

D = 25

Multiply both by four if you want to.
