Answer:

Step-by-step explanation:


Divide both sides by 4:


Answer:
78 : 162 = 13 : 27. These two equalities are examples of proportions (equal ratios); it is as simple as that.
Answer:

Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases
So equation will be


Therefore, equation representing the proportional relationship will be
