The ratio of adults to children attending a new exhibit at the museum was found to be 8:5. Based on this ratio, if 390 people attended one day, how many would be children?
the fastest method would be to add 8+5 and then divide 390 by it. And then that would be your base unit which you multiply to 8 and 5 to get your answers
8+5=13 390/13 30 30x8=240 adults 30x5=150 children
