Question
How many tens are there in the sum of 65 + 9?
5
6
7
8
Hint:
lace value can be defined as the value represented by a digit in a number on the basis of its position in the number .For example, the place value of 7 in 3,743 is 7 hundreds or 700. However, the place value of 7 in 7,432 is 7 thousands or 7,000.
The correct answer is: 7
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. Here, 65 + 9 = 74 In 74, 7 is in tens place. Thus 7 is the correct answer.
