Answer:
151/1000
Step-by-step explanation:
To convert 15.1 percent to a fraction follow these steps:
Step 1: Write down the percent divided by 100 like this:
15.1% = 15.1/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,
15.1/100 = (15.1 x 10)/(100 x 10) = 151/1000.
(This fraction is alread reduced, We can't reduce it any further).
<span><span>Let x = amt of water evaporated
.05(50) = .08(50-x)
2.5 = 4 - .08x
.08x = 4 - 2.5
.08x = 1.5
x =
x = 18.75 lb of water evaporated
Check; amt of salt remains the same, only the percentage is different, right?
.05(50) = .08(50-18.75)
.05(50) = .08(31.25)
2.5 = 2.5</span><span>
