How many tens are there in the sum of 65 + 9?

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.
