**Reiny**, Wednesday, September 3, 2008 at 7:58amok, let's do it without algebra

so far he has given away 1/2, 1/4 and 1/5 of the herd

1/2 + 1/4 + 1/5

= 10/20 + 5/20 + 4/20

= 19/20 of the herd, leaving 1/20

but it said the 4th son get 7 cows, so he must have received 1/20

then if 1/20 equals 7 then

20/20 , or the whole herd, must have been 20x7 or 140 cows

check:

1/2 of 140 = 70

1/4 of 140 = 35

1/5 of 140 = 28

sum of 70+35+28+7 = 140
