Alright, lets get started.
Suppose 1 barrel of the grass contains amount of grass = x
The bisons at the city zoo are fed [tex] \frac{3}{8} [/tex] of a barrel of grass each day.
Means bisons are fed amount of grass = [tex] \frac{3}{8} x [/tex]
The elephants are fed [tex] \frac{7}{3} [/tex] as much grass as the bisons.
Means amount of grass elephants are fed per day = [tex] \frac{7}{3} *\frac{3}{8}x [/tex]
Means amount of grass elephants are fed per day =[tex] \frac{7}{8}x [/tex]
[tex] \frac{4}{7} [/tex] of a week means = [tex] 7*\frac{4}{7} = 4 [/tex] days
Means amount of grass elephants are fed in 4 days = [tex] 4*\frac{7}{8}x = \frac{7}{2}x [/tex]
It means [tex] \frac{7}{2} [/tex] barrels of grass are fed to elephants in 4 days. : Answer
Hope it will help :)
