Place the first digit
Decide where to place the first digit in
the quotient.
83>26 so there are enough tens. So,
place the first digit in the tens place.
Divide. 83 26
Multiply. 3 26 78
Subtract. 83 78 5
5<26
Divide the ones.

Divide. 52 26
Multiply. 26 2 52
Subtract. 52 52 0
Check the answer.
32 26 832, it checks.

2. Have the students use the method shown
to practice dividing 3-digit numbers by 2-digit
numbers.

Problem:
At a movie theater, 50 cents for each adult ticket and 25 cents for each child ticket is put in a reserve fund.
Today, 141 adults watched a movie and the number of children who watched a movie is not known. If 7,900
cents were put in the reserve fund, then find how many children watched a movie. Write the solution and
answer.
Answer:
Amount put in the reserve fund from adult tickets 50 141 7,050 cents
Amount put in the reserve fund from child tickets 7,900 7,050 850 cents
