1 - вся земля; 3/5 всей земли отведено под пашню, из них 3/4 засеяно зерновыми

1) 3/4 = 36 га - засеяно зерновыми. Находим целое по его части:

36 : 3 * 4 = 48 (га) - земля, отведённая под пашню;

2) 3/5 = 48 га - отведено под пашню. Находим целое по его части:

48 : 3 * 5 = 80 (га) - вся земля на хуторе. 

Ответ: на хуторе 80 га земли.
