___

Answer 1

To solve the subtraction problem 95 - 43 using the strategy of modeling with base ten units, we will proceed step-by-step.

1. Line up the place values:

   • The problem is structured as follows:

       95
      -43
     -----
     

2. Model the minuend:

   • We represent 95 using base ten units of 9 tens and 5 ones.

3. Subtract the ones:

   • We start by subtracting the ones. We have 5 ones in 95, and we need to subtract 3 ones (as 43 has 3 in the ones place).
   • Grey out 3 ones, which leaves us with 2 ones.

4. Subtract the tens:

   • Next, we move on to the tens. We have 9 tens in 95, and we need to subtract 4 tens (as 43 has 4 in the tens place).
   • Grey out 4 tens from 9 tens, which leaves us with 5 tens.

5. Final calculation:

   • After grey-out, we are left with 5 tens and 2 ones.
   • We can combine these to find that 95 - 43 equals 52.

So, we can represent the final answer as follows:

       95
      -43
     -----
      52

Filling in the blanks:

• Line up the place values, and use base ten units.
• Grey out 3 ones to subtract them.
• Grey out 4 tens to subtract them.
• The answer is 52.
