Question

During the weekend, it snowed `2/5` of a foot of snow in `1/4` of the day. At that rate how much did it snow in an entire day?

Answer 1

During the weekend, it snowed `1 3/5` feet in an entire day,

Explanation:

You already know that it snowed `2/5` of a foot in a quarter of the day. You are trying to determine how much it snowed in an entire day, which is otherwise known as: how much it snowed in a whole day (`1/1`).
Since you know that the rate of the snowfall is `2/5` of a foot for every quarter (`1/4`) of the day, you can just simply multiply by 4 to get the rate for the whole day because there are four quarters (`1/4`) in a whole (`1`)

Hope this helps! :)
