Noa was walking in the forest and measured the circumference of two trees that he found. the first tree measured 37 5/8 inches around, and the second tree measured 45 1/3 inches around. noa wanted to find the difference of the circumferences of the two trees. he recorded his steps in the table.

step 1: 45 1/3- 37 5/8
step 2: 45 8/24 - 37 15/24
step 3: 44 32/24 - 37 15/24
step 4: 44 32/24 - 37 15/24= 8 17/24

in which step did noa first make an error?

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.

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

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