1935 people visit a library during one week. the ratio children : adults is 1 : 4 how many more adults than children visited the library?

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.
