David&dan share a lottery win of £9900 in the ratio 3:2 David then shares his part between himself, his wife and their son how much more does his wife get over their son

Step-by-step explanation:

The question is incomplete. The complete question is:

David & Dan share a lottery win of £9900 in the ratio 3 : 2. David then shares his part between himself, his wife & their son in the ratio 4 : 4 : 2. How much more does his wife get over their son?

Solution:

David & Dan share a lottery win of £9900 in the ratio 3 : 2. The total ratio is 3 + 2 = 5

The amount that David got would be

3/5 × 9900 = £5940

Therefore, £5940 was shared in the ratio of 4 : 4 : 2. The total ratio is 4 + 4 + 2 = 10

The amount that his wife gets is

4/10 × 5940 = £2376

The amount that his son gets is

2/10 × 5940 = £1188

The amount that his wife gets over their son is

2376 - 1188 = £1188

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
