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
