please help! The ratio of the number of adults to the number of children on a cruise was 13:6. The ratio of girls to the total number of children was 2:5. If there were 198 boys on the cruise, what was the total number of passengers?

Answer: 1,045 passengersStep-by-step explanation:This question involves multiple steps. Let's first try to figure the number of children on the cruise.The ratio of girls to the total number of children was 2:5. There are 198 boys.This information tells me that for every 5 children, there's 2 girls and 3 boys.Based off of this information, we can divide the total number of boys by 3 in order to find the number of children.198÷3=66Let's multiply 66 by 5 since that's the number of groupings based off the ratio.66×5=330Let's check the number of children. Since the ratio of girls to total children is 2:5 and we already confirmed there's 198 boys, there should be 132 girls. We can turn this ratio into a fraction where 2/5 of the children are girls. we can confirm this by multiply 330 by 2/5 (0.4) and getting 132.There are 330 children on the cruise.The ratio of the number of adults to the number of children was 13:6.For every 6 children, there were 13 adults. Let's divide the number of children by 6 in order to find the number of groupings.330÷6=55Let's now multiply the groupings by 13 to find the number of adults.55×13=715So there should be 715 adults and 330 children on the cruise.715+330=1,045
