Part B: Fill in the Blank
Write the correct answer on each line.
1. 240 can be shown as 2 hundreds and 4 tens.
240 is 200 + 40, where 40 equals 4 tens, so there are 4 tens after the 2 hundreds.
2. 240 can also be shown as 24 tens.
240 equals 20 tens plus 4 tens, giving 24 tens in total when you count every group of ten.
3. 1 hundred, 2 tens, and 13 ones equals 133.
100 plus 20 plus 13 equals 133, since the 13 ones add 10 more to the tens and leave 3 ones.
4. The number 306 has 30 tens when you break it into tens and ones.
300 equals 30 tens, and 306 also has 0 extra tens and 6 ones, so there are 30 tens total.
5. 2 hundreds, 15 tens, and 4 ones equals 354.
200 plus 150 plus 4 equals 354, since 15 tens is 150 and adds another hundred to the total.
