    Answer:

    Step 4: 44 32/24 – 37 15/24= 8 17/24

    Explanation:

    Circumference Tree 1 = 37 5/8 inches around

    Circumference Tree 2 =  45 1/3 inches around

    Step 1: 45 1/3- 37 5/8

    The measures are correct, no issues copying them.

    Step 2: 45 8/24 – 37 15/24

    Noa looked for common denominators

    1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

    Step 3: 44 32/24 – 37 15/24

    Noa looked for making the fraction part higher on the left side:

    45 8/24 = 44 32/24 is correct because 24/24 = 1

    Step 4: 44 32/24 – 37 15/24= 8 17/24  

    Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.
