isilah masing masing pembilang pecahan pada ruas sebelah kanan berikut ini,agar di peroleh pernyataan yang benar. please jawab yang benar dan tepat menggunakan

ini langsung caranya, soal tidak ditulis lagi ya (langsung dikali silang)

a)( 15y²z . x) ÷ (5y)
= (5y . 3yz . x) ÷ (5y)
= 3xyz

b) (14y . 2x) ÷ 7
= (7 . 2y . 2x) ÷ 7
= 2y . 2x
= 4xy

c) (12z³ . xy ) ÷ 3z
= (3z . 4z . xy) ÷ 3z
= 4z . xy
= 4xyz

d) (45c³ . 5ab) ÷ 9c
= (9c . 5c² . 5ab) ÷ 9c
= 5c² . 5ab
= 25abc²

e) (8a²b . (a + b)) ÷ (2ab)
= 2ab(4a . (a + b)) ÷ (2ab)
= 4a(a + b)

f) (3x + y)(3m²n³) ÷ mn
= (3x + y). mn(3mn²) ÷ mn
= (3x + y)(3mn²)

g) 8x²(x - y)(9xy) ÷ 4(x - y)
= 2x(4(x-y)(9xy)) ÷ 4(x - y)
= 2x(9xy)
= 18x²y

h) (6xy - 15y)(x - 4) ÷ (2x - 5)
= 3y(2x - 5)(x - 4) ÷ (2x - 5)
= 3y (x - 4)

a)( 15y²z . x) ÷ (5y)
= (5y . 3yz . x) ÷ (5y)
= 3xyz

b) (14y . 2x) ÷ 7
= (7 . 2y . 2x) ÷ 7
= 2y . 2x
= 4xy

c) (12z³ . xy ) ÷ 3z
= (3z . 4z . xy) ÷ 3z
= 4z . xy
= 4xyz

d) (45c³ . 5ab) ÷ 9c
= (9c . 5c² . 5ab) ÷ 9c
= 5c² . 5ab
= 25abc²

e) (8a²b . (a + b)) ÷ (2ab)
= 2ab(4a . (a + b)) ÷ (2ab)
= 4a(a + b)

f) (3x + y)(3m²n³) ÷ mn
= (3x + y). mn(3mn²) ÷ mn
= (3x + y)(3mn²)

g) 8x²(x - y)(9xy) ÷ 4(x - y)
= 2x(4(x-y)(9xy)) ÷ 4(x - y)
= 2x(9xy)
= 18x²y

h) (6xy - 15y)(x - 4) ÷ (2x - 5)
= 3y(2x - 5)(x - 4) ÷ (2x - 5)
= 3y (x - 4)
