Which of the following interchanges in signs will make the given equation correct?
17−15×5=250
- A= and ×
- B+ and −
- C= and −
- D× and −
Solution & Step-by-step Explanation
Let's test the options to see which interchange balances the equation:
Check option D (× and −):
Replace − with × and × with −:
17×15−5=255−5=250
Since 250=250, this option is correct.
Check option D (× and −):
Replace − with × and × with −:
17×15−5=255−5=250
