Hi,

Let the number of movies Joan has be x.

It is given that half of Joan's video collection consists of 8 science fiction movies.

In mathematical notation, half (1/2) of Joan's video collection (x) consists of 8 science fiction movies.

or

(1/2) of x = 8

x/2 = 8

Multiply both sides by 2.

2 * x/2 = 8 * 2

x = 16

Hope this helps!

Edit:

Just to add.

(1/2) of x = 8

In this case, "of" is similar to multiply. So,

(1/2) of x = 8

can be represented as

(1/2) * x = 8
