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

1161

Step-by-step explanation:

From the question, ww are told that 1935 people visit a library during one week and the ratio of children to adult is 1:4.

This means that the fraction of children is 1/5 qnd the fraction of adult is 4/5. Since there are 1935 people, the number of children will be:

= 1/5 × 1935

= 387

The number of adults will be:

= 4/5 × 1935

= 1548

To find the number of more adults than children that visited the library, we subtract 387 from 1548. This will be:

= 1548 - 387

= 1161

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
