solution

Each part in the first picture is

1

8

.

Each part in the second picture is

1

2

.

+

The

1

8

pieces are not the same size as the

1

2

pieces. So, you can't add the shaded parts yet.

However, you can redraw the second picture so each part is

1

8

,

too. You can see that

1

2

is equivalent to

4

8

.

=

In the equation, replace the second picture with

4

8

.

Now the shaded parts are the same size and you can add them.

+

=

The sum is
