A model with 4 shaded sections and 6 unshaded sections.

A model with 40 shaded sections and 60 unshaded sections.

Step-by-step explanation:

Required:

Which models shows 40%

(a) 4 shaded and 6 unshaded

First, we calculate the total sections

The percentage of the shaded section is:

(b) 40 shaded and 60 unshaded

First, we calculate the total sections

The percentage of the shaded section is:

(c) 2 shaded and 8 unshaded

First, we calculate the total sections

The percentage of the shaded section is:

Hence, (a) and (b) shows 40%

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
