Answer: 53.1%

----------------------------

Explanation:

The change from 76.1 to 116.5 is 40.4
This means that 40.4 more million people voted in the second year compared to the first

Divide this difference (40.4 million) over the original amount (76.1 million) to get

40.4/76.1 = 0.53088 which converts to 53.088% and that rounds to 53.1%

Josh can paint a whole room in m hours while Kevin can paint a whole room in n hours. How many parts of the room can they paint
Leona [35]
<h3>Answer: (m+n)/(mn)</h3>

Work Shown:

Josh:

1 room = m hours

1/m room = 1 hour

Kevin:

1 room = n hours

1/n room = 1 hour

We see that the rates for Josh and Kevin are 1/m and 1/n respectively. This is the amount of a room they paint in one hour. Combine the fractions

1/m + 1/n = n/(mn) + m/(mn) = (n+m)/(mn) = (m+n)/(mn)

The expression (m+n)/(mn) represents how much of the room they get painted in 1 hour. This is if they work together and it assumes neither worker slows the other one down.
