How do you convert a sampling rate by non integer factor?

To enable this process the non-integer factor has to be approximated by a rational number: Hence, the sampling-rate conversion is achieved by interpolating by L i.e. from 44.1 kHz to [44.1x160] = 7056 kHz. Then decimating by M i.e. from 7056 kHz to [7056/147] = 48 kHz.

Is resampling the same as interpolation?

Resampling is used to either increase the sample rate (make the image larger) or decrease it (make the image smaller). Interpolation is the process of calculating values between sample points. So, if you resample an image you can use interpolation to do it.

Is it possible to Upsample the signal?

Upsampling is the process of inserting zero-valued samples between the original samples of a signal to increase the sampling rate. One way to accomplish upsampling by an integer ratio of 1:D is to interpose D-1 zero samples between each pair of the input samples of the signal.
