Yes. That statement is true.
For example in : (1/2) divided by (3/4), you would invert 3/4 to make 4/3 and change the divide symbol to the multiply symbol. Becoming:
(1/2) multiplied by (4/3)<em> = </em><em>(1/2) divided by (3/4) = 0.66r</em>
        
             
        
        
        
Answer:
The average speed is 36.67 m/h
Step-by-step explanation:
100/50 = 2
120/30 = 4
Total time = 6
Total distance = 220 miles
220/6 = 36.67

Answer:
Line M - neither 
Line N - parallel
Line P - perpendicular
Line Q - neither
Step-by-step explanation:
If a line is perpendicular to another, the slope will be the opposite, e.g. -6, opposite slope, -6.
If a line is parallel to another, the slope will be the exact same, e.g. -6, same slope, 1/6.
