volume_mute
Select all problems where the trailing-zeros shortcut can be applied (i.e., the divisor has at least one ending zero).
Correct Answer
(1) \(9{,}800 \div 350\)
(2) \(47{,}000 \div 100\)
Explanation
The shortcut applies when the divisor ends in zeros. 350 ends in one zero ✓ and 100 ends in two zeros ✓. The divisors 23 and 6 have no trailing zeros, so the shortcut cannot be applied to those problems.
