Question

Annmarie spends 1/2 of her paycheck on rent, 1/5 on food, and 1/16 on utilities. What fractional part of her paycheck does she have left for other expenses?

Answer 1

She is left with 19/80 of her paycheck

Explanation

What I did to get this answer is added together the amount she spent on her expenses and then subtract that from the whole check,

1/2 = 40/80

1/5=16/80

1/16= 5/80

when added 40/80 + 16/80 + 5/80 = 61/80

we subtract 61/80 from a whole and are left with 19/80's meaning that she has 19/80's left of her paycheck to pay for other expenses
