Solution:

Concept:

Let the missing value be

x

. Use inverse operations to isolate

x

.

Explanation:

Given:

\frac{\frac{17.28}{x}}{3.6 \times 0.2}=200

.

Simplify denominator:

3.6 \times 0.2 = 0.72

.

So,

\frac{17.28}{x \times 0.72}=200

.

Cross-multiply:

17.28 = 200 \times 0.72 \times x

.

Now,

200 \times 0.72 = 144

.

Thus,

x = \frac{17.28}{144} = 0.12

.

Answer:

The missing number is

0.12

, so the correct option is D.
