Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

1st son = 1/2 x (Given)

2nd son = 1/4 x (Given)

3rd son = 1/5 x (Given)

4th son = 7 cows (Given)

Find the fraction of the cows that the 4th son got:

1 - 1/2 - 1/4 - 1/5 = 1/20

Form the equation and solve for x:

1/20 x = 7

20/20 x = 7 x 20

x = 140

Answer: x = 140
