Brianna's work Gavin's work
Step 1: Subtract (20×23) from 552 to get 92. Step 1: Subtract (10×23) from 552 to get 322.
Step 2: Subtract (4×23) from 92 to get 0. Step 2: Subtract (10×23) from 322 to get 92.
Step 3: Add partial quotients. Step 3: Subtract (2×23) from 92 to get 46.
Step 4: Subtract (2×23) from 46 to get 0.
Step 5: Add the partial quotients.
Part A
Which student(s) correctly calculated the quotient? Explain your answer.
Both Brianna and Gavin correctly calculated the quotient.
Brianna correctly followed the steps of long division by subtracting multiples of 23 from 552 until she reached a remainder of 0. She then added up the partial quotients to get the final quotient.
Gavin also correctly followed the steps of long division by subtracting multiples of 23 from 552 until he reached a remainder of 92. He then subtracted more multiples of 23 from 92 until he reached a remainder of 0. Lastly, he added up the partial quotients to get the final quotient.
