That CAN'T be true! / What is "four times less"?
« on: 02/11/2023 20:33:36 »
I've just seen a TV advert for a detergent that requires "four times less scrubbing" to remove grease.
Now one times A equals A so one times less A = 0. No problem with that.
But what does 4 times less A mean? Does the detergent remove the grease from next week's dinner too?
