00:00:03.320 --> 00:00:10.600
3050020 is equal to 3000000 plus what plus 20?
00:00:12.320 --> 00:00:20.360
The number 3050020 has been partitioned into three parts.
00:00:22.120 --> 00:00:24.560
The first part is 3000000.
00:00:26.160 --> 00:00:30.160
The three digit in this number represents 3000000.
00:00:32.080 --> 00:00:36.960
The third part that our number has been partitioned into is 20.
00:00:38.280 --> 00:00:46.240
The two digit in 3050020 is worth two tens or 20.
00:00:48.160 --> 00:01:00.200
The second part of the partitioned number must be the digit five because all of the other digits in 3050020 are zeros.
00:01:01.680 --> 00:01:06.920
So we need to use our knowledge of place value to find out what this five digit is worth.
00:01:08.800 --> 00:01:10.760
This digit represents the ones.
00:01:12.320 --> 00:01:14.440
This digit represents the tens.
00:01:16.080 --> 00:01:18.200
This digit represents the hundreds.
00:01:19.600 --> 00:01:21.680
This digit is the thousands.
00:01:22.720 --> 00:01:26.400
So this digit represents the ten thousands.
00:01:28.400 --> 00:01:35.240
The five digit represents five ten thousands, which is 50000.
00:01:36.840 --> 00:01:38.880
The missing number is 50000.
00:01:39.400 --> 00:01:47.800
3050020 is equal to 3000000 plus 50000 plus 20.
00:01:49.920 --> 00:01:53.240
We used our knowledge of place value to help us find the answer.
00:01:54.080 --> 00:01:56.840
Our number had been partitioned into three parts.
00:01:58.000 --> 00:02:03.080
We’ve recognised that only three digits in this number weren’t zeros.
00:02:04.320 --> 00:02:06.480
The three was worth 3000000.
00:02:07.960 --> 00:02:10.840
The two is worth two tens, which is 20.
00:02:12.160 --> 00:02:14.400
We had to work out what the five was worth.
00:02:16.400 --> 00:02:19.720
We’ve realised that five was in the ten thousands column.
00:02:20.920 --> 00:02:23.920
Five ten thousands is 50000.
