How to change width of product image and Product Short Description areas

Hi, in sales junction on the woocommernce single product page, how can I adjust how much page width is allocated to the product image (left side) as opposed to the product title, short description, price etc Area (right side)? I would rather a 50 / 50 split.
Thank you

I would like to use a smaller image and enable the text area to the right to be wider (where it says diploma of business/study now etc)
