Answer 1

Oi...

a)

(- 3/5xyz²) ÷ (0,2yz)

- 3/5xyz² ÷ (2/10yz)

- 3/5xyz² ÷ (1/5yz)

- 3/5xyz² ÷ yz/5

- 3/5xyz² × 5/yz

- 3xz

b)

(0,2x²y⁴) ÷ (0,25xy²)

(2/10x²y⁴) ÷ (25/100xy²)

(1/5x²y⁴) ÷ (1/4xy²)

x²y⁴/5 ÷ xy²/4

x²y⁴/5 × 4/xy²

xy²/5 × 4

4xy²/5

c)

(100a²b³c⁴) ÷ (0,01abc)

100a²b³c⁴ ÷ (1/100abc)

100a²b³c⁴ ÷ abc/100

100a²b³c⁴ × 100/abc

100ab²c³ x 100

10000ab²c³

d)

(b²m²) ÷ (- 5bm)

- b²m²/5bm

- bm/5

e)

(- 250x³) ÷ (50x³)

- 5
