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)
1 answer
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.
