Explanation:
We need to write the following ratios with its simplest form.
1.
Factors of 21 = 3, 7
Factors of 28 = 2, 7, 2
2.
Factors of 96 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
Factors of 32 = 1, 2, 4, 8, 16, 32
3.
Factors of 22 = 1, 2, 11, 22
Factors of 33 = 1, 3, 11, 33
4.
Factors of 12 = 1, 2, 3, 4, 6, 12
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
5.
Factors of 72 = 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Factors of 56 = 1, 2, 4, 7, 8, 14, 28, 56
6.
Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54
Factors of 63 = 1, 3, 7, 9, 21, 63
Hence, this is the required solution.
