If you're solving for W, your answer is w = 2 1/6
First, we would simplify our fractions:
w + 2/3 = 2 5/6 =
w + 2/3 = 17/6
Lastly, we subtract 2/3 on both sides of the equation:
w + 2/3 - 2/3 = 17/6 - 2/3 =
w = 13/6 or w = 2 1/6
<span>Rate of pump A: 1/8 of a pool per hour
Rate of pump B: 1/9 of a pool per hour
Combined rate: 1/8+1/9 = 17/72 +1/9 = 25/72
So if they work together, the two pumps have a combined rate of 25/72 of a pool per hour (i.e in one hour, the two pumps will empty 25/72 of the pool)
</span><span>But we want to empty ONE pool (not 25/72 of one). So we need to multiply 25/72 by some number x to get 1.
</span>
<span>Now solve for x
x=2.88
</span><span>It will take the two pumps 2.88 hours to empty the pool.
2 hours 52 minutes 50 seconds</span>
-18 because 2 1/4 as an improper fraction is 9/4 then it -8/1 then multiply which is -72/4 and simplified is -18.
