responsive grid: different column widths-CodePudding

was wondering if the following is possible using grid or flexbox.

I got a 3-column layout that I want to make responsive. Now, on the one hand I can use a media query to lets say make all 3 columns full width on <640px screens, but what if I want the first 2 to be 50/50 and the third one full width? A possible solution could be to use a combination of a media query and :last-child, but I wonder if this can be done without the use of media queries?
