To solve the problem step by step:
- We start with the equation \(357 - 14\).
- Subtracting 1 ten from the 5 tens leaves us with 4 tens (since \(5 - 1 = 4\)).
- Subtracting 4 ones from the 7 ones leaves us with 3 ones (since \(7 - 4 = 3\)).
- The 3 hundreds is subtracting no hundreds, so \(3 - 0 = 3\).
Putting it all together:
- The result is \(3\) hundreds, \(4\) tens, and \(3\) ones.
So, we get the difference of \(343\).
Thus, the filled-in blanks are: 3, hundreds, 343.
