Sure. Jasminder has made 55% of the recipes in a particular cookbook, which means he has not made 45% of the recipes. If there are 9 recipes that he has never made, this means that 45% of the recipes in the cookbook is equal to 9. We can set up a proportion to find the total number of recipes:
45% ---- 9 recipes
