some marbeles are share among 3boys.Aaron’s share 3/4 of Brian’s share and Brian’s share is 4/5 of Charle’s share. If Aaron and Brian have a toatl 56 marbles altogether.How many marbles do the 3 boys have in all?

heyy auntie persis,
im claire, i used to b in yr math class for P6?
im having trouble with on how to inverse a fraction.. i can inverse a expression but not so sure on fractions.
like for an example,
f(x)=1/ 3x+4

Hi, Claire,
I suppose you are asking about how to inverse a function in the form of a fraction. There is a general method to inverse a function. First we let y=f(x), and then we try to express x in terms of y. For example,
let , then express in terms of .
Thus, we have

.
Then we change everything from to by convention, we have
.
That would be your inverse function to the original function.

A : B : C

3 : 4 : 5

A+B —> 7 u —-> 56

1 u —-> 8

Altogether: 12 u —> 12 x 8 = 96 marbles
