Students at Oak Hill School sold some tickets for a concert at the county festival. They have 36 tickets left to sell. The number of tickets that the students started with is a 3-digit number. The number of tickets that they sold is a 2-digit number. What could the numbers be?
Show your work. Write an equation.
Answer:
Let the 3 digit number be x
The given clue is they started with three digit number
and they sold two digit number so left is 36
101 – 36 = 65
According to the clues
IF the 3 digit number is 101
And number of tickets sold is 65
101 – 65 = 36
so, 36 tickets left.
Turn and Talk Explain how you would choose numbers if the starting number of tickets and the number of tickets sold are both 3-digit numbers.
Answer:
Number of tickets left is also a 3 digit number.
Explanation:
If the starting number of tickets and the number of tickets sold are both 3-digit numbers.
Then the numbers we assume is 800 – 400 = 400

Answer:
Regrouping is done by making groups of tens during operations like subtraction and addition.
Regrouping means rearranging numbers into groups by place value to make it easier to carry out operations.
This process is called regrouping because you’re rearranging numbers into place value to carry out the process.
