LenKa [72]

Answer:

33.3333% decrease

Step-by-step explanation:

Percent change formula: \frac{(x-y)}{|y|} *100, where x is the new value and y is the starting value.

Plug in values and solve:

\frac{20-30}{30} *100\\\frac{-10}{30} *100\\-0.3333*100\\

-33.3333% change, or a 33.3333% decrease.

aliina [53]
The answer is 85%.

If you're solving without a calculator, you can simply multiply the numerator and denominator so that the denominator is equal to 100. So, for this fraction, you would multiply both the top and the bottom by 5.

17/20
17(5) / 20(5)
85 / 100
85%
