Answer:
Step 1
Explanation:
Mark simplified 3/5 + 5/8 using the steps below:
Step 1: 3/5 * 8/5
Step 2: 3 * 8 / 5 * 5
Step 3: 24/5
Step 4: 4 4/5
Mark's error is in Step 1 where he changed the addition sign to multiplication sign.
The correct solution is:
![Step 1: (3)/(5)+ (5)/(8)\\Step 2: (24+25)/(40)\\Step 3: (49)/(40)\\Step 4: 1(9)/(40)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/i5xpna0f4nrls23ee7dsd931ja9dwejg7z.png)
