Question

A field of grass lasts100 cows 20 days . About how many days will it last for 250 cows?

Answer 1

50 i believe

Answer 2

you take 20% of 250 so yes 50 is correct

Answer 3

100 cows= 20 days
5 cows = 1 day
250 cows= 50 days

Answer 4

the answer is 7.5

Answer 5

how did you get that answer?

Answer 6

i didnt

Answer 7

you cant say 5 cows eat grass in 1 day because when you decrease the number of cows the number of days is supposed to increase

Answer 8

surely it will be less than 100 days and less than 50 - there 2 1/2 times more cows in same size field

Answer 9

right right i see
100x20=2000
250X=2000
X=8

Answer 10

nono cows and days are inversely related and the field is constant

Answer 11

i believe its 8

Answer 12

if 100 cows take 20 days to eat aall the grass
1 cow 2000
so 250 takes 2000 / 250 = 8 days

Answer 13

correct nerd

Answer 14

yes its inverse variation
