4 Algebra problems, can I please get some help? (With steps to solve each one!)

------- x ----- ÷ -----
c²d² ab c²d³
First perform multiplication:
(a³b²c / abc²d²) ÷ a / c²d³
In dividing fractions. Get the reciprocal of the 2nd fraction and multiply it to the 1st fraction.
a/c²d³ is the 2nd fraction. Its reciprocal is c²d³/a
So,
a³b²c c²d³ a³b²c³d³
------------ x --------- = -------------- = abcd *cancel out like terms
abc²d² a a²bc²d²
b) (6x / 4x -16) ÷ (4x / x² -16)
(6x / 4x-16) × (x²-16 / 4x)
6x(x² - 16) / 4x(4x-16)
6x³ - 96 / 16x² - 64x
c) 3x² - 6x x + 3x² *use distributive property of multiplication
--------------- × -------------
3x + 1 x² -4x + 4
3x² (x+3x²) - 6x (x + 3x²) ⇒ 3x³ + 9x⁴ - 6x² - 18x³
3x (x² - 4x + 4) + 1(x² -4x +4) ⇒ 3x³ -12x² + 12x + x² -4x + 4
9x⁴ + 3x³ - 18x³ - 6x² ⇒ 9x⁴ - 15x³ - 6x²
3x³ - 12x² + x² + 12x - 4x + 4 ⇒ 3x³ - 11x² + 8x + 4
d) 2x² - 10x + 12 2 + x
---------------------- × -----------
x² - 4 3 - x
2(2x² - 10x + 12) + x (2x² - 10x + 12) ⇒ 4x² - 20x + 24 + 2x³ -10x² + 12x
3(x² - 4) - x(x² -4) 3x² - 12 - x³ + 4x
2x³ + 4x² - 10x² - 20x + 12x + 24 ⇒ 2x³ - 6x² - 8x + 24
-x³ + 3x² + 4x - 12 -x³ + 3x² + 4x - 12

The number of visits for which they will earn the same money is: 20 visits
How to solve Algebra word problems?
We are told to denote the number of visits by v.
Now, we are told that:
Fitness center A charges $50 plus $2 per visit. Thus, the equation to find the amount for v number of visits is:
2v + 50
Now, we are told that another fitness center B charges $30 plus $3 per visit. Thus, the equation to find the amount for v number of visits is:
3v + 30
Thus, the number of visits for which they will earn the same money is:
2v + 50 = 3v + 30
3v - 2v = 50 - 30
v = 20 visits

A. 21/75B. 75/21C. 7/25D. 7/9
Answers
Because 7/15 ÷ 3/5 = (7 × 5) / (3 ×15) = 7/9
7/15 / 3/5
Keep ====> 7/15
Change =====> *
Flip ====> 5/3
Now multiply
7/15 * 5/3 = 35/45
35/45 = 7/9
Answer: 7/9

1/2=0.500000000000........
Therefore:
2/3 > 1/2
The answer is yes because the fraction 2/3 is greater than 2/4.
Is 2/3 greater than 2/4?
To compare 2/3 and 2/4, we need to find a common denominator.
The least common multiple (LCM) of 3 and 4 is 12. So, we can rewrite the fractions with a common denominator:
2/3:
= (2/3) * (4/4)
= 8/12
2/4:
= (2/4) * (3/3)
= 6/12
Therefore, the answer is yes because the fraction 2/3 is greater than 2/4.
