Rasterizing an existing image to lower ppi

I don’t know if this is even possible to calculate somehow, but maybe someone can help. If i have a 200ppi image in a file, and i want it to keep the size, but have 150 ppi, is there a way to calculate what ppi i have to use for rasterizing? I am aware that rasterizing an image from 200 ppi to 150 ppi will not give out the same result as rasterizing a vector object to 150 ppi.

Again, for example

Vector object > rasterize 150 ppi > object with certain “pixel density”
200 ppi image > rasterise ? ppi > object with same pixel density as option 1 (150 ppi) < is this even possible?

@martink15467522 You can select an image, select Crop and set the PPI in the Control panel and hit enter

That works, but the new image still has lower quality then the original 150 ppi one because it rasterizes the image twice ( rasterizing from 200ppi to 150ppi gives lower quality than from vector to 150 ppi)
