(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
5ab-2ab+4a-b+5b = 3ab+4a+4b
4a + 3a = (4 + 3)a = 7a
3a * * * * * Actually, it is 4a.

(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
It is -44 + 4a
5ab-2ab+4a-b+5b = 3ab+4a+4b
a2 - 4a + 4
48a3 + 32a2 + 4a = 4a(12a2 + 8a + 1)
4a4 + 11a3 - 47a3 - 4a + 5 =4a4 - 36a3 - 4a + 5 =4a (a3 - 9a2 - 1) + 5
4a + 3a = (4 + 3)a = 7a
10a + 3a - 4a = 9a
5x - 8a + 4a - 2x + a = 3x - 3a
3a * * * * * Actually, it is 4a.
It is an expression of two terms as: 4a+12
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
