There are two parts to the following question. First, answer part A. Then, answer part B. Brianna and Gavin used partial quotients to show 552÷23 . See their work below. 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. (2 points)
Both Brianna and Gavin correctly calculated the quotient. They both used partial quotients to subtract multiples of 23 from the dividend until they reached 0.
