Answer 2

It seems like you are providing a mathematical expression, but it's not entirely clear what you're asking for. Let me break down the expression you provided and solve it step by step:

$7 \frac{1}{2} : 2 \frac{1}{2} \times 3 \frac{2}{3} - 5 \frac{1}{5} \times \frac{5}{13} \times (1 \frac{1}{2})^3$

First, let's simplify the fractions and exponents:

$7 \frac{1}{2} = 7.5$

$2 \frac{1}{2} = 2.5$

$3 \frac{2}{3} = 3.67$ (approximately)

$1 \frac{1}{2} = 1.5$

Now, perform the calculations:

1. Division: $7.5 : 2.5 = 3$

2. Multiplication: $3 \times 3.67 = 11.01$ (approximately)

3. Multiplication of fractions: $\frac{5}{5} \times \frac{1}{13} = \frac{1}{13}$

4. Cube the result: $1.5^3 = 3.375$

Finally, subtract the two results:

$11.01 - (5.1 \times 3.375) \approx 11.01 - 17.143 = -6.133$ (approximately)

The result of the given expression is approximately $-6.133$.
