Okay, let's break this down step-by-step:
* 90% of 90 girls showed up on time
* 90% is 0.9
* 0.9 * 90 is 81 girls on time
* The total number of girls is 90
* So the number of girls late is 90 - 81 = 9
* 80% of 110 boys showed up on time
* 80% is 0.8
* 0.8 * 110 is 88 boys on time
* The total number of boys is 110
* So the number of boys late is 110 - 88 = 22
* The total number of children late is the girls (9) + the boys (22)
* So the total number
