Given that the ratio of children to adults is 1:4 out of 1935 people.
Determine how many more adults than children visited the library.
Work:
Divide 1935 by 5.
1935/5 = 387
So now that we have the total amount of people that visited the library per 1:4 ratio.
Then, multiply both sides by 387 to find out how many children and adults visited the library.
387 x 1 = 387
387 x 4 = 1548
That means, the exact ratio of children to adults is 387:1548.
Lastly, subtract the amount of children from the total amount of adults to find out exactly how many more adults visited the library.
1548 - 387 = 1161
Thus, 1,161 more adults visited the library than children.
