Expert writing Tips

Best practice

In less formal contexts, "four times less" is generally understood, but be mindful of your audience and the potential for misinterpretation.

Common error

Avoid assuming "four times less" means subtracting four times the original value. It usually means reducing something to one-fourth of its original value. For example, if you misinterpreted it to mean subtracting, starting from 100 you will end up with -300, while the correct answer should be 25.
