Question

(-7/12)*(-6/7)*(-5/6)*(-4/5)*(-1/4)

Answer 1

Ответ:

- 1/12

Пошаговое объяснение:

- (7*6*5*4*1)/(12*7*6*5*4) (это типо дробь)

7, 6, 5, 4 сокращаются. Остаётся сверху 1, снизу 12. Знак минус, так как он повторяется пять раз.

Answer 2

To calculate the expression (-7/12)(-6/7)(-5/6)(-4/5)(-1/4), you can simplify the fraction multiplication step by step:

(-7/12)(-6/7) equals (7/12)(6/7) since multiplying two negative numbers gives a positive result, and the negative signs cancel out. = (76)/(127) = 42/84

Now, let's continue with the next fraction:

(42/84)(-5/6) = (42(-5))/(84*6) = -210/504

Proceeding to the next fraction:

(-210/504)(-4/5) = (210/504)(4/5) = (2104)/(5045)

Simplifying the numerator and denominator further:

= 840/2520 = 1/3

Finally, multiply the remaining fraction by the last fraction:

(1/3)(-1/4) = (1(-1))/(3*4) = -1/12

Therefore, the result of the expression (-7/12)(-6/7)(-5/6)(-4/5)(-1/4) is -1/12.
