Ludwig's WRAP-UP

In summary, "decrease proportionally" is a grammatically sound and relatively common adverbial phrase used to describe a reduction that maintains a consistent ratio with another quantity. As Ludwig AI confirms, it’s used correctly when there's a clear and demonstrable proportional relationship. While versatile, this phrase is most frequently encountered in scientific and academic contexts, where precision is paramount. When writing, ensure you are clearly establishing the proportional relationship to avoid ambiguity.
