It is stated that: If a divisor has ending zeros, we can simplify the division by removing the same number of ending zeros from both the divisor and the dividend.
Apply this definition to simplify:
\(-2{,}400 \div 60\)
What is the equivalent, simplified division to perform?
Correct Answer
\(-240 \div 6\)
Explanation
The divisor 60 has one trailing zero, so remove one zero from each:
\[-2{,}400 \div 60 = -240 \div 6 = -40\]
Check with original: \(-40 \times 60 = -2{,}400\) ✓
