When you subtract signed numbers, such as 5 - (-3), you keep the first number, change the operation to addition and change the sign of the second number, i.e., 5 + (+3) = 8.
When you divide fractions, such as (1/2) / (2/3), you keep the first fraction, change the operation to multiplication and change the second fraction to its reciprocal, i.e., (1/2) * (3/2) = (3/4)
