Answer:

(1) 1.2 inches

Given:
Initial dog treat: 8 inches in length, 3.2 inches in width.
Miniature dog treat: 3 inches long,? wide

We will apply cross multiplication to find the proportionality:

Relating length and width.
Original treat: 8/3.2
Miniature treat: 3/x

8/3.2 = 3/x

Cross multiply:
8 * x = 3.2 * 3
8x = 9.6

Calculate x
x = 9.6/8
x = 1.2

The width of the miniature dog treat measures 1.2 inches.

To verify:
original treat: 8/3.2 = 2.5
miniature treat: 3/1.2 = 2.5
or:
8/3.2 = 3/1.2
8 * 1.2 = 3.2 * 3
9.6 = 9.6
