In Yellowstone National Park there are 300 species of birds that migrate. This accounts for 2/7 of all the species of birds sigh
Juli2301 [7.4K]

Answer:

\frac{2}{7} x = 300

Step-by-step explanation:

Let x = the number of all the species of birds sighted in the park

“300 species of birds that migrate. This accounts for 2/7 of all the species of birds sighted in the park”

the above sentence means “(2/7)x = 300”

now we can solve it :

(2/7)x = 300

⇔ 2x = 7×300

⇔ 2x = 2100

⇔ x = 2100/2

⇔ x = 1050
