Jeff gave 1/4 of a sum of money to his wife. then he divided the remainder equally among his 4 children.
a) what fraction of the sum of money did each child receive
b)if each child received $600, find the sum of money

A) The fraction of sum of money did each child receive is

B) The sum of money did Jeff have $ 3200

Step-by-step explanation:

Given as :

Let The sum of money did Jeff have = $ x

The fraction of money did Jeff's wife get = of $ x

The remaining money Jeff will have = $ x - of $ x

I.e The remaining money Jeff will have =

                                                                =

A ) The remaining amount of money is divided equally among 4 children

So, The fraction of sum of money did each child receive =

I.e The fraction of sum of money did each child receive =  

B ) If each child will receive $ 600

∴,   = $ 600

Or, 3 x = $ 600 × 16

Or, 3 x = $ 9600

∴    x =

I.e  x = $ 3200

So, The sum of money did Jeff have $ 3200  

Hence ,

A) The fraction of sum of money did each child receive is

B) The sum of money did Jeff have $ 3200   Answer

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

thats not a system of equations, that is a solution
