a). 200 species = (4/7) of (All)
Multiply each side by 7 . . . 1400 species = (4) x (All)
Divide each side by 4 . . . All = 1400species/4 . . . All = 350 species
b).
Birds = 350 species
Plants = 600 species
There are more species of plants than of birds in the park.
Because 600 is greater than 350.
