Answer:

Step-by-step explanation:

If Skylar has 4 times as many books as Karen, that means that you have to do a division problem to figure out how books Karen has. Because Skylar has 4 times as many books, and she has 164 books, the division problem is 164÷4=41 books.

igor_vitrenko [27]

Answer:

£390

Step-by-step explanation:

The ratio of money in bank:

Terry : Faye

3 : 7

Terry put £220 in his account

Faye withdrew £300 from her account

Unknown:

Initial amount Terry had = ?

Solution:

Let the real amount terry has = 3x

Faye will have = 7x

Now;

3x + 220 = 7x -300

Solving this equation:

3x + 220 = 7x -300

3x - 7x = -300 - 220

-4x = - 520

4x = 520

x = 130

Originally, Terry has 3x = 3 x 130 = £390
