There are 300 students at a school who have been asked to attend assembly. 1/10 students are sat on chairs, 85% of students are sat on the floor, the rest do not attend assembly. How many students did not attend assembly?

300 x 1/10

= (300/10) x 1

= 30 students sat on chairs

85% of 300 

= (300/10) x 8.5

= (30 x 8) + (30 x 0.5)

= 240 + 15

= 255 students sat on the floor

Students who did not attend = 300 - 30 - 255

= 15
