v=2\ m/s\\\\E_k=16\ J=16\ \frac{kgm^2}{s^2}\\\\E_k=\frac{mv^2}{2}\\\\\frac{m\cdot(2\ m/s)^2}{2}=16\ \frac{kgm^2}{s^2}\\\\\frac{m\cdot4\ m^2/s^2}{2}=16\ \frac{kgm^2}{s^2}\\\\2m\ m^2/s^2=16\ \frac{kgm^2}{s^2}\ \ /:2\ m^2/s^2\\\\m=8\ kg-answer

TL;DR(too long didn't read): answer is 3/4


This question may look confusing, however, it is more easily understood once you see that the fractions appear to be changing more randomly than they are in a way you can recognize, however, they're not. Since they look like that it's because they're being multiplied by a fraction. Split the fractions into two to make it easier. 3/2 and 9/8, just look at them as '3' and '2' and '9' and '8'. 3 becomes 9. Which means either 6 was added or 3 was multiplied by 3. Compare to the next row, 27. 9-->27 can't be 6, so it's being multiplied by 3. Now for the bottom. 2 becomes 8, and knowing that the numerator of the fraction is being multiplied, so is the denominator then, so 2-->8 is 2 times 4. Put the numerator and denominator back together and you have 3/4. The answer is 3/4.

Sam can his job in 20 min. So he can do the whole job at the rate of 1 job in 20 minutes.
So he does 1/20 of the job per minute.

Rob can do the job in 30 min. His rate is 1/30 of the job per minute.
.
Working together how long does it take?
.
1/20*x + 1/30*x = 1 job done
, where x = minutes.

Multiply everything by 60 to get rid of the fractions.
3x + 2x = 60
5x = 60
.
Divide both sides by 12
x = 12
.
So the answer for working together it will take them 12 minutes.
