Part B: Fill in the Blank
Write the missing number on each line.
1. The value of the 3 in 36 is 30.
The digit 3 is in the tens place, so its value is 3 x 10 = 30.
2. 7 tens and 5 ones = 75.
In 75, the tens digit is 7 and the ones digit is 5.
3. 60 + 8 = 68.
68 minus 60 equals 8, so the missing ones value is 8.
4. The number 49 has 9 ones.
In 49, the tens digit is 4 and the ones digit is 9.
5. 80 + 2 = 82.
82 minus 2 equals 80, so the missing tens value is 80.
