➢ To find how many pupils are there in the room, we need to divide the percentage and the number of pupils so we can get the total answer.

  • [tex]\tt\color{green}{ \: \: \: \: \: \: \: \: \: 50} \ \ \\\tt{26}|\overline{\tt1300 \: \: \: \: } \\ \tt\underline{\: \: \: 130 \: \: \: \: } \\ \: \: \: \: \: \: \: \: \: \tt{0}[/tex]

⟹ Therefore, the total number of pupils are there in the room will be, 50.
