A school is going on a field trip to a museum. The ratio of men to women to children is 1:3:20 and there are 216 people on this trip. What is the difference between the number of children and adults?

The difference between the number of children and adults=153

Step-by-step explanation:

ratio of men to women to children is 1:3:20

Total RATIO = 1+ 3+ 20= 24

Number of men = ratio of men / Total ratio x  Total Number of people on the trip =

= 1/24 x 216= 9 men

Number of women=ratio of women / Total ratio x  Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women

Number of children=ratio of Children/ Total ratio x  Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children

The difference between the number of children and adults will be 180 -27 = 153

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
