I bake. A lot. so adding fractions is important to see how many cups I need. It also helps with weighing foods and multiplying recipes to see how many ingredients I need. math help when I go out with my friends and we agree to split the bill evenly because we need to divide it. or when you want to give a tip to your server and you need to see what 10% of your bill is. Math helps for measuring walls. we painted my room this summer and had to measure the walls to put in new beams and to see how much paint we might need.
