If a gardener can mow a lawn in 25 min, what portion of the lawn can the gardener mow in 1 min?

She can mow 1/25 or 0.04 or 4% of the lawn in 1 minute.

To find the portion of the lawn that the gardener can mow in 1 minute, we need to calculate the fraction of the lawn the gardener mows in 25 minutes.

First, we know that the gardener can mow the entire lawn in 25 minutes. So, if we assume that the lawn is a standard size and the gardener is working at a constant speed, we can say that the gardener mows 1/25th of the lawn in one minute.

Therefore, the gardener can mow 1/25th or 0.04 (4%) of the lawn in 1 minute.
