<h3>What is Division?</h3>
It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here,
total hour practicing = 87 hours
Daily hours for practicing = 3 hours
total number of days = n days
Now, according to question;
n X 3 = 87
87 ÷ n = 3
Thus, the equation which represent number of days is 87 ÷ n = 3.
