Answer:
Step 4: 44 32/24 - 37 15/24= 8 17/24
<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>
Step-by-step explanation:
1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.
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
<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>
