Answer:
[tex]\frac{17}{40}[/tex] in simplest form.
Step-by-step explanation:
Figure out how much 1/3 of her income is to figure out the rent
Her full income is $1600 a month so to find what 1/3 is we need to multiply that number by the decimal number of 1/3.
1/3 = 0.33
$1,600 x 0.33 = $480 for rent
Now let's do the same process for her groceries.
1/8 = 0.125
$1600 x 0.125 = $200 for groceries
Now let's find the fraction form!
[tex]\frac{Rent + Groceries}{Monthly Income}[/tex] = [tex]\frac{480 + 200}{1800}[/tex] = [tex]\frac{680}{1800}[/tex]
Let's not forget to put it in simplest form!
[tex]\frac{680}{1600}[/tex] = [tex]\frac{17}{40}[/tex]
That's our answer!
Good Luck!
