Question
How many ones are there in the sum of 69 + 28?
- 9
- 8
- 7
- 6
Hint:
Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that children understand that whilst a digit can be the same, its value depends on where it is in the number.
The correct answer is: 7
Here, 69 + 28 = 6 tens 9 ones + 2 tens 8 ones
Add the digits in ones place:
9 (ones)
+ 8 (ones)
________
1 (tens) 7 (ones)
Thus, there are 7ones in the sum of 69 + 28.
