Simplify the following please. Been a very long time since I have had to do this and need as much help as possible.
1: (-15a^2b) ÷ (5a)
2: 4(-3a)(b)( -2c)
3: (m - 1)(2m - 5)
Need help with possibly explanation on how to answer the following math questions.?

1:
(-15 a^2 b) ÷ (5 a)
= (-15/5) a^(2 - 1) b
= -2 a b
====
2:
4(-3a)(b)(-2c)
= +(4*3*2)abc
= 24abc
===
3:
(m - 1)(2m - 5)
= m(2m - 5) - (2m - 5)
= 2m² - 5m - 2m + 5
= 2m² - 7m + 5
(-15 a^2 b) ÷ (5 a)
= (-15/5) a^(2 - 1) b
= -2 a b
====
2:
4(-3a)(b)(-2c)
= +(4*3*2)abc
= 24abc
===
3:
(m - 1)(2m - 5)
= m(2m - 5) - (2m - 5)
= 2m² - 5m - 2m + 5
= 2m² - 7m + 5

1.
- 15 a² b
-------------- = - 3 a b
5 a
2.
24 a b c
3.
m² - 5m - 2m + 5 = m² - 7m + m
- 15 a² b
-------------- = - 3 a b
5 a
2.
24 a b c
3.
m² - 5m - 2m + 5 = m² - 7m + m
