Hello, There are endless expressions. Since, you multiply this fraction by a costant k / k
If k = 2
Then,
(5/9) = ( 5/9) × ( k / k)
= (5/9) × ( 2/2)
= (5 × 2 / 9×2)
= 10 / 18
________________
The only restriction for k is zero and the infinite. Because there is no "0/0" and "infinito/ infinito" at math.
Answer: 360minutes
Step-by-step explanation:
Speed = space/time ; time = space/speed
space = 600km
speed: 100km/h
time = 600km/100km/h = 6hours
Since 1hour = 60minutes
6hours = 6x60minutes = 360 minutes
Answer: 360minutes

Answer:
See proof below
Step-by-step explanation:
An equivalence relation R satisfies
- Reflexivity: for all x on the underlying set in which R is defined, (x,x)∈R, or xRx.
- Symmetry: For all x,y, if xRy then yRx.
- Transitivity: For all x,y,z, If xRy and yRz then xRz.
Let's check these properties: Let x,y,z be bit strings of length three or more
The first 3 bits of x are, of course, the same 3 bits of x, hence xRx.
If xRy, then then the 1st, 2nd and 3rd bits of x are the 1st, 2nd and 3rd bits of y respectively. Then y agrees with x on its first third bits (by symmetry of equality), hence yRx.
If xRy and yRz, x agrees with y on its first 3 bits and y agrees with z in its first 3 bits. Therefore x agrees with z in its first 3 bits (by transitivity of equality), hence xRz.
