Question

1/2 : (-2/3) : 3/4 : (-4/5) : 5/6

Answer 1

1/2:(-2/3)=1/2*(-3/2)=3/4
3/4:3/4=3/4*4/3=1
1:-4/5=-5/4
-5/4*6/5=-6/4=-1и1/2

Answer 2

The given sequence can be written as:

1/2 : -2/3 : 3/4 : -4/5 : 5/6

This sequence consists of fractions with alternating signs. Let's break down each fraction:

1/2 = 0.5 -2/3 = -0.666... 3/4 = 0.75 -4/5 = -0.8 5/6 = 0.833...

So, the sequence can be written as:

0.5 : -0.666... : 0.75 : -0.8 : 0.833...

Alternatively, if you want to express the sequence in fraction form:

1/2 : -2/3 : 3/4 : -4/5 : 5/6
