Addition and subtraction requires that we find a common demoninator.
For example,
The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.
Then we add the numerators
Then we should reduce.
Division is a little trickier because we have to flip-flop the second term and then multiply. For example: 
Answer:
Each person paid $24.
Step-by-step explanation:
1. Find 20% of 40. Since 20% is equal to 1/5, we can divide 40 by 5 to get 8. Together they tipped $8.
2. We know that the total amount they paid was $48, so we divide that in half to get the answer. 48 divided by 2 is 24.
