Answer:

(x -10)/7

Step-by-step explanation:

As with division of numerical fractions, you can do it by multiplying by the inverse of the divisor. Similarly, as with division of numerical fractions, when the denominators are the same, the quotient is the ratio of the numerators.

$\dfrac{x-10}{35x +21}\div\dfrac{7}{35x +21}=\boxed{\dfrac{x-10}{7}}$

Given:

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

To find:

The area of old growth trees.

Solution:

We have,

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

Area of old growth trees is

$Area=0.4\% \text{ of total forest area}$

$Area=\dfrac{0.4}{100}\times 52000$

$Area=0.4\times 520$

$Area=208$

Therefore, the area of old growth trees is 208 acres.
