Answer:

1 % decrease

Step-by-step explanation:

The percent of decrease time can be written as the expression $\frac{200}{200}-\frac{198}{200} = \frac{2}{200}.$ Now, we convert the fraction into a decimal: $\frac{2}{200} = \frac{1}{100} = 0.01.$ We can convert this decimal into a percentage: 0.01*100 = 1%.

STatiana [176]

Answer:

It would be <u>97.50</u> square deckles.

Step-by-step explanation:

Given:

On the distant plant, Mathology, a sports area covers 7400 yodels².

1 deckle = 75.9 yodels.

Now, to get the square deckles.

As given, 1 deckle = 75.9 yodels.

So, to get the square deckles by using conversion factor:

<em>75.9 yodels = 1 deckle.</em>

7400 yodels² = $7400\div 75.9$

= $97.50\ deckels ^2.$

Therefore, it would be 97.50 square deckles.
