  1. Problem 1
    1. You partition 23 it is 20 and 3.
    2. Write 20 x 3=60 and write 4 x 3=12.
    3. Add 60 and 12 and it =72

    It will help you because I know that 20 x 3=60 and 4 x 3=12

  2. What milly has done is that she first knows
    4times 20 is 80. And then it was 4 times 3
    is 12 but the important question was 4 times 23.what she did she partitioned

    23.the answer was 93
