Explanation:

Step1: Analyze the chart structure

The chart has rows starting with 1, 11, 21, ..., 91 (tens place: 0, 1, 2, ..., 9; ones place: 1) and ends with 10, 20, ..., 100 (ones place: 0). Each row has 10 columns, so we can fill numbers by incrementing by 1 in each column.

Step2: Fill the first row (tens=0, ones from 1 - 10)

First row: 1 (given), then 2, 3, 4, 5, 6, 7, 8, 9, 10 (given). So columns 2 - 9: 2, 3, 4, 5, 6, 7, 8, 9.

Step3: Fill the second row (tens=1, ones from 1 - 10)

Second row: 11 (given), then 12, 13, 14, 15, 16, 17, 18, 19, 20 (given). Columns 2 - 9: 12, 13, 14, 15, 16, 17, 18, 19.

Step4: Fill the third row (tens=2, ones from 1 - 10)

Third row: 21 (given), then 22, 23, 24, 25, 26, 27, 28, 29, 30 (given). Columns 2 - 9: 22, 23, 24, 25, 26, 27, 28, 29.

Step5: Fill the fourth row (tens=3, ones from 1 - 10)

Fourth row: 31 (given), then 32, 33, 34, 35, 36, 37, 38, 39, 40 (given). Columns 2 - 9: 32, 33, 34, 35, 36, 37, 38, 39.

Step6: Fill the fifth row (tens=4, ones from 1 - 10)

Fifth row: 41 (given), then 42, 43, 44, 45, 46, 47, 48, 49, 50 (given). Columns 2 - 9: 42, 43, 44, 45, 46, 47, 48, 49.

Step7: Fill the sixth row (tens=5, ones from 1 - 10)

Sixth row: 51 (given), then 52, 53, 54, 55, 56, 57, 58, 59, 60 (given). Columns 2 - 9: 52, 53, 54, 55, 56, 57, 58, 59.

Step8: Fill the seventh row (tens=6, ones from 1 - 10)

Seventh row: 61 (given), then 62, 63, 64, 65, 66, 67, 68, 69, 70 (given). Columns 2 - 9: 62, 63, 64, 65, 66, 67, 68, 69.

Step9: Fill the eighth row (tens=7, ones from 1 - 10)

Eighth row: 71 (given), then 72, 73, 74, 75, 76, 77, 78, 79, 80 (given). Columns 2 - 9: 72, 73, 74, 75, 76, 77, 78, 79.

Step10: Fill the ninth row (tens=8, ones from 1 - 10)

Ninth row: 81 (given), then 82, 83, 84, 85, 86, 87, 88, 89, 90 (given). Columns 2 - 9: 82, 83, 84, 85, 86, 87, 88, 89.

Step11: Fill the tenth row (tens=9, ones from 1 - 10)

Tenth row: 91 (given), then 92, 93, 94, 95, 96, 97, 98, 99, 100 (given). Columns 2 - 9: 92, 93, 94, 95, 96, 97, 98, 99.

Answer:

The filled chart (partial example for clarity, full filling follows the above steps):

1	2	3	4	5	6	7	8	9	10
21	22	23	24	25	26	27	28	29	30
31	32	33	34	35	36	37	38	39	40
41	42	43	44	45	46	47	48	49	50
51	52	53	54	55	56	57	58	59	60
61	62	63	64	65	66	67	68	69	70
71	72	73	74	75	76	77	78	79	80
81	82	83	84	85	86	87	88	89	90
91	92	93	94	95	96	97	98	99	100

(The numbers made are all two - digit numbers from 1 - 99 (with appropriate tens and ones) and 100, following the tens and ones place value system.)
