Answer 1

Answer:

12 days

Step-by-step explanation:

6 oxen = 8 cows

1 ox=8/6 cows

$9 \: oxen = ( \frac{8}{6} \times 9)cows$

9 oxen = 12 cows

9 oxen + 2cows =12 cows + 2cows

9 oxen + 2cows =14 cows

8 cows can graze a field = 21 days

1 cow can graze a field = 21×8

14 cows can graze a field =

$\frac{21 \times 8}{14} = 12\: days$
