To add and subtract fractions you have to have the denominators as the same number. Say you have 1/2 - 1/4 and you need to solve. You will need to make the denominators the smallest number that they both go into. In this case, they both go into 4.
Since the fraction we need to change, 1/2, has a numerator of 2, and 2 times 2 is four, you need to multiply the numerator and denominator by 2. Then you get 2/4. Now subtraction is easy!
Subtract the numerators and keep the denominator. 2/4 - 1/4 = 1/4
Answer:
The answer is C because the domain is all your x-coordinates.
Step-by-step explanation:
Initial balance : 463.76
refunds : 12.56 + 52.11 + 26.03 = 90.70
sales : 101.32 + 10.98 = 112.30
463.76 - 90.70 + 112.30 = 485.36 is the correct balance
so there is a (511.39 - 485.36) = 26.03 difference
so the mistake made was instead of subtracting the 26.03 refund, she added it as a sale
