A man left 3/7 of his money to his wife, 1/2 to his brother and the rest of it he divided equally among his 3 children.If each of children received $400, how much did his wife receive?
3/7= Money for the Wife
1/2 of remains to Brother
The rest divided equally between 3 kids, each child receiving $400, together $1200.
Now imagine there are 7 blocks of the money and 3 are for the wife
The brother: 1/2 x 4/7(which is the remaining)
The brother receives 2 blocks
The children get 2 blocks
The children's $1200 divided by 2(blocks) is $600 for each block
This means the brother get $1200
and the wife gets $1800
