Divide by 2 – Digit Divisors
   People in the United States eat about 23 pounds of pizza
    per person each year. If you ate that much pizza each
    year, how many years would it take you to eat 775 pounds
    of pizza?
   Use partial quotients to solve. 775 ÷ 23

18. About how many years would it take for a
  person in the United States to eat 855 pounds
  of apples?
21. In a study, 9 people ate a total of 1,566
  pounds of potatoes in 2 years. If each person
  ate the same amount each year, how many
  pounds of potatoes did each person eat in 1
  year?
 How can you use partial quotients to divide
 by 2-digit divisors?
   Patterns and basic facts can help you estimate quotients by using
    compatible numbers.
 Estimate money
