Ответ:

Пошаговое объяснение:

(-7/8)*(-9/4)*(1/54)=(-7*(-9)*1)/(8*4*54)=(7*9)/(8*4*9*6)=7/192.

Answer 2

(-7*(-9)*1)/(-8*(-4)*54)=63/1728
Дробь можно сократить на 9:
(63/9)/(1728/7)=7/192

Answer 3

To solve this mathematical expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Now, let's calculate the expression step by step:

Step 1: Start with the multiplication and division operations.

-7/8 * (-9/4) * 1/54

Step 2: Multiply the fractions:

(-7/8) * (-9/4) = 63/32

Step 3: Divide by 1/54:

(63/32) * (1/54)

To divide by a fraction, you can multiply by its reciprocal:

(63/32) * (54/1) = 63 * 54 / (32 * 1) = 3402 / 32

Step 4: Simplify the fraction:

3402 divided by 32 is 106 with a remainder of 10, so the result is:

3402/32 = 106 + 10/32 = 106 + 5/16

Therefore, the final answer is:

-7/8 * (-9/4) * 1/54 = 106 + 5/16 or 106.3125 (in decimal form).
