Final answer:

To subtract 143-79 by breaking apart, round 79 to 80, subtract it from 143 to get 63, and add 1 back for rounding to get the final answer of 64.

Step-by-step explanation:

The question involves breaking apart numbers to subtract 143-79. This is a technique used in math to simplify subtraction by splitting numbers into parts that are easier to work with.

Step-by-Step Explanation:

  1. First, let's round 79 to the nearest tens, which is 80.
  2. Now, subtract 80 from 143: 143 - 80 = 63.
  3. Since we rounded up 79 to 80, we subtracted one extra unit from 143. So, we need to add that 1 back to the result: 63 + 1 = 64.

The final answer is 64.
