Answer:

Step-by-step explanation:

12======

Let her total money salary be 1

Money she spends = 1/3

Remaining salary = 1 - 1/3 = 2/3

Money she saves = 3/8 of remainder = 3/8 * 2/3 = 1/4

Money she spends on her family members = 1 - ( 1/3 + 1/4)

= 1 - ( 4/12 + 3/12)

= 1 - 7/12 = 5/12

So, 5/12 of her salary is spent evenly among her 3 family members

So, each of them gets 1/3 of 5/12 of her salary

So, our fraction is

1/3 * 5/12

Fraction= 5/36

Answer 2

Total Height of the tree = Height of the building + 1/3 part of tree
let the height of the tree is x
ATQ
x= 12+x/3
x=36+x/3
3x=36+x
3x-x=36
2x=36
x=18
So the total height of the tree is 18 m.
