Verified answer

1) 2y/4b= y/2b

2) 10x²/15a= 2x²/3a

3) 12b/18x= 2b/3x

4) 24b³/32m= 3b³/4m

5) 20n²/5x= 4n²/x

6) 0,3a/0,1c²= 3a/c²

1) 2y/4b = (2y : 2)/(4b : 2) = y/2b = 0,5yb⁻¹

2) 10x²/15a = (10x² : 5)/(15a : 5) = 2x²/3a = 2/3 x²a⁻¹

3) 12b/18x = (12b : 6)/(18x : 6) = 2b/3x = 2/3 bx⁻¹

4) 24b³/32m = (24b³ : 8)/(32m : 8) = 3b³/4m = 0,75b³m⁻¹

5) 20n²/5x = (20n² : 5)/(5x : 5) = 4n²/x = 4n²x⁻¹

6) 0,3a/0,1c² = (0,3a : 0,1)/(0,1c² : 0,1) = 3a/c² = 3ac⁻²
