1/4

Step-by-step explanation:

To find fractions that are equivalent to 2/8 we can multiply it by other fractions equal to 1.

Fractions that are equal to 1 will look like x/x, never x/y.

The numerator and denominator will always be the same.

For example we could multiply 2/8 by 2/2.

The numerators multiply together and the denominators do.

We would get

2/8*2/2=4/16

(2*2)=4

(2*8)=16

Or we could also simplify this fraction.

We can do that by dividing the numerator and denominator by the same whole number. (Dividing it by 1.)

So let's divide both the numerator and denominator by 2.

(2/2)=1

(8/2)=4

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
