In Yellowstone National Park there are 300 species of birds that migrate. This accounts for 2/7 of all the species of birds sighted in the park.

Write an equation to find the number of species of birds that have been sighted in Yellowstone National Park.

x = 300

300x =

300x =

x = 300

Total number of species of birds sighted at Yellowstone National park is 1050.

Step-by-step explanation:

Let's assume M represents number of species of birds that migrate and S represents total number of species of birds sighted at Yellowstone National park

The data provided can be written in numerical form as M is 2/7th of S

M = 2/7 * S

300 = 2/7 * S

2100 = 2 * S

1050 = S

S = 1050 total number of species of birds sighted in the Yellowstone National park
