Mr. Hughes gave 5/14
of his savings to his son, 2/3 of the remainder to his daughter, and the rest to his wife.
If his wife got $900, what were his savings?

Sagot :

Answer:

His savings were of $4,200.

Step-by-step explanation:

Mr. Hughes gave 5/14 of his savings to his son, 2/3 of the remainder to his daughter, and the rest to his wife:

This means that the son and daughter amount is:

[tex]\frac{5}{14} + \frac{2}{3}(\frac{9}{14})[/tex]

As [tex]\frac{9}{14}[/tex] is the remained that his son did not get. So

[tex]\frac{5}{14} + \frac{2}{3}(\frac{9}{14}) = \frac{15}{42} + \frac{18}{42} = \frac{33}{42}[/tex]

Fraction his wife got:

[tex]1 - \frac{33}{42} = \frac{42}{42} - \frac{33}{42} = \frac{9}{42}[/tex]

If his wife got $900, what were his savings?

Total savings are x, wife got [tex]\frac{9}{42}[/tex] of x. So

[tex]\frac{9x}{42} = 900[/tex]

[tex]9x = 900*42[/tex]

[tex]x = \frac{900*42}{9}[/tex]

[tex]x = 100*42[/tex]

[tex]x = 4200[/tex]

His savings were of $4,200.
