I would first express the denominator in millions -> 8.076 billion * 1,000 = 8,076 million. Then, since we're looking for a percentage I would multiply the numerator by 100 to begin with instead of doing it at the end -> 53.42 million * 100 = 5,342 million. Then simplify to get your answer, which is already in percentage format:

5,342/8,076 which is approximately 2/3 = 0.66%

Answer is C.

5,342/8,076 which is approximately 2/3 = 0.66%

Answer is C.

Answer = C) 0.66%

Let all values be in Millions

8.076 Billions =  8.076 * 10^3  Millions = 8076 Millions

Percentage  = \frac{53.24}{8076} * 100 = \frac{5324}{8076} = 0.66%

Since 1 billion is 1000 million

Soc changing all quantities to million
 Finland forest area =53.42 million hect.
 Worlds's forest area =8.076 billion hect.

% =53.42*100/8.076*1000 =0.66%

Approximation

Approximation is a strategy that helps us arrive at less than an exact number and the inclusion in this problem of the word “approximately” is an obvious clue. First, 8.076 billion is 8,076 million. Next, 8,076 million rounds to 8,000 million and 53.42 million rounds to 53 million. Dividing 53 million by 8,000 million we arrive at 0.0066 (53M/8,000M). We convert this decimal figure to a percentage by multiplying by 100 (or moving the decimal point two places to the right) and adding a percent sign in order to obtain our answer of 0.66%. Note that the shortcut method involves comparing 53 million to 1% of 8,000 million or 80 million. Since 53 million is approximately two-thirds of 80 million then the answer is some two-thirds of 1% or 0.66%.

Answer: C.

mvictor · Answer

I tried to approximate:
53,420,000/8,076,000,000
we can remove 4 zero's from top and bottom:
5342/807600
ok, let's approximate:
5000/800000
simplify by 1000.
5/800
ok, so this is easier.
divide 5 by 8, and get 0.625.
now, 0.625/100 is 0.625% or aprox. 0.66%. so C.
