Explanation:
The given ratio of the money divided among three people is 15:18:7. We can write this ratio as:
15x : 18x : 7x
where x is a common factor for all three terms.
Let's assume that the smallest share of the money is 133. Then, we can write:
7x = 133
Solving for x, we get:
x = 19
Substituting the value of x in the ratio, we get:
15x : 18x : 7x = 285 : 342 : 133
Therefore, the total sum of money is:
285 + 342 + 133 = 760
And the largest share of money is:
18x = 342
Hence, the total sum of money is 760 and the largest share of money is 342, given that the smallest share is 133.
