In what way will you apply proportion to solve real life problems?
We can use proportions to solve real-world problems by using the following steps: Use the information in the problem to set up two ratios comparing the same quantities. One of your ratios will contain the unknown. Set the ratios equal creating a proportion.
How do you think proportions help in our everyday life?
For example, it is very common to use a half or double of a recipe. In this case, people use proportions and ratios to make correct calculations for each ingredient. If a recipe calls for 2/3 of a cup of flour, the cook has to calculate how much is half or double of 2/3 of a cup.
