jonny [76]

Answer:

The question would've given you to what number you should round up your answer.

Answer is:

Whole number:

63%

1 decimal place:

63.3%

2 decimal places:

63.33%

Exact number:

$\frac{190}{3}$ %

Step-by-step explanation:

So the starting no. = 30

Ending no. = 11

In order to evaluate the percentage of decrease we:

(Ending number/starting number) * 100

So:

$\frac{11}{30} *100 = \frac{11}{3} *10 = \frac{110}{3}%$ %

To find the Decrease percentage:

100 % - 110/3 %

= 63.333%
