0,64•0,081•0,5 ———————— 0,09•0,25•0,16

To simplify the expression \(\frac{0.64 \times 0.081 \times 0.5}{0.09 \times 0.25 \times 0.16}\), we can first compute the values of the numerator and the denominator separately.

Numerator: \[ 0.64 \times 0.081 \times 0.5 \] Calculating step-by-step:

1. \(0.64 \times 0.081 = 0.05184\)
2. \(0.05184 \times 0.5 = 0.02592\)

So, the numerator is \(0.02592\).

Denominator: \[ 0.09 \times 0.25 \times 0.16 \] Calculating step-by-step:

1. \(0.09 \times 0.25 = 0.0225\)
2. \(0.0225 \times 0.16 = 0.0036\)

So, the denominator is \(0.0036\).

Now, substituting the values back into the expression: \[ \frac{0.02592}{0.0036} \]

Dividing these two numbers: \[ 0.02592 \div 0.0036 = 7.2 \]

Thus, the value of the given expression is: \[ \boxed{7.2} \]
