Grade 4 - Word Problems - Solving Word Problems with Decimals

When solving word problems involving decimals, it’s helpful to use a structured approach to compare and compute values. In this example, we have three individuals—Franz, his father, and his mother—each with different heights measured in meters. By setting up equations with known values and using basic operations like addition and subtraction, we can determine who is the tallest and by how much.

The process involves aligning decimal points carefully and using placeholders to ensure accurate calculations. Once the heights are calculated, comparing them directly allows us to identify the tallest person. Additionally, encouraging the use of letters to represent different quantities fosters algebraic thinking, which is essential as students progress in their mathematical education.
