Question

55 per cent of the student in a school are girs. what percentage of the student are boys? find the number of the student , if there are 216 boys​

Answer 1

Respuesta:

55% + 45% = 100%

We already know that 216 is the 45% of the students. So,

  x   =   216  

55          45

The result of this is 216 x 55 = 264

                                    45

There are 480 students. 216 boys (45%) and 264 girls, (55%).
