Question

3/4:(-4/5):5/6(-6/7):7/8​

Answer 1

Ответ:

1 5/49

Пошаговое объяснение:

3/4:(-4/5):5/6(-6/7):7/8​ = 1 5/49

1. 3/4 : (-4/5) = 3/4 * (-5/4) = -15/16

2. -15/16 : 5/6 = -15/16*6/5 = -9/8

3. -9/8 * (-6/7) = 27/28

4. 27/28 : 7/8 = 27/28* 8/7 = 54/49 = 1 5/49

Answer 2

To simplify the expression 3/4 : (-4/5) : 5/6 : (-6/7) : 7/8, you need to perform the division operations and simplify the fractions:

1. First, perform the divisions from left to right:

(3/4) : (-4/5) = (3/4) * (-5/4) = -15/16 (-15/16) : (5/6) = (-15/16) * (6/5) = -45/32 (-45/32) : (-6/7) = (-45/32) * (-7/6) = 315/192 (315/192) : (7/8) = (315/192) * (8/7) = 540/343

So, the simplified result of the expression 3/4 : (-4/5) : 5/6 : (-6/7) : 7/8 is 540/343.
