A) 3:4
B) 4:7
C) 5:9
To solve this, we need to find the Greatest Common Divisor (GDC) of each pair of numbers.
For pair A)
Factors:
39 => 1, 3 13, 39
52 => 1, 2, 4, 13, 26, 52
The GCD is 13. Then divide both numbers by the GCD:
39/13 = 3
52/13 = 4
The SImplified ratio is 3:4
For B)
Factors:
44 => 1, 2, 4, 11, 22, 44
77 => 1, 7, 11, 77
Then divide by GCD, in this case, 11:
44/11 = 4
77/11 = 7
44:77 => 4:7
For c)
Factors:
45 => 1, 3, 5, 9, 15, 45
81 => 1, 3, 9, 27, 81
The GCD is 9. Then
45/9 = 5
81/9 = 9
The ratio is 45:81 => 5:9
