Each week i save half my pocket money and i buy stamps for my collection with 1/3 of the pocket money. that leaves $3.21. how much do i spend on stamps?

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
