To simplify the expressions, we need to find the greatest common factor in each ratio.
A. 3a - 7b : a + bIn this ratio, the greatest common factor is 1. Therefore, the simplified ratio is:(3a - 7b) : (a + b)
B. 2a + 9b : 2a + 5bIn this ratio, the greatest common factor is 1. Therefore, the simplified ratio is:(2a + 9b) : (2a + 5b)
To simplify the expressions, we need to find the greatest common factor in each ratio.
A. 3a - 7b : a + b
In this ratio, the greatest common factor is 1. Therefore, the simplified ratio is:
(3a - 7b) : (a + b)
B. 2a + 9b : 2a + 5b
In this ratio, the greatest common factor is 1. Therefore, the simplified ratio is:
(2a + 9b) : (2a + 5b)
