The total students in the grade is 210.

Explanation:

Given :

Students in band = 63 students

Band students represent = 30% of the students in the class

To find :

The total students

Solution :

Let the total students in the grade be as y

`\bigstar \:\boxed{\sf{30\% \: of \: y = 63}}`

`\sf{\implies} \: (30)/(100) * y = 63 \\ \\ \sf{\implies} \: (30y)/(100) = 63 \\ \\ \sf{\implies} \: 30y = 63 * 100 \\ \\ \sf{\implies} \: 30y = 6300 \\ \\ \sf{\implies} \: y = (6300)/(30) \\ \\ \sf{\implies} \: y = 210`

Total Students = 210

`\therefore` The total students in the grade is 210.
