M.m.c (30, 60, 300)
30, 60, 300|3
10, 20, 100|2
5, 10, 50 |5
1, 2, 10 | ===> 3*2*5 = 30

Shouldnt there be a picture or something?
The gcf of 12/15 is 3 (simplest terms is 4/5)
Step-by-step explanation:
Let's say b is the rate of the boat in still water, and c is the rate of the current.
Distance = rate × time
Going upstream:
100 = (b − c) (5)
20 = b − c
Going downstream:
100 = (b + c) (2)
50 = b + c
Solve the system of equations using substitution or elimination. Using elimination, add the equations together:
70 = 2b
b = 35
c = 15
The boat's speed is 35 km/h, and the current's speed is 15 km/h.
That would be 13.25, 13+1/4
= 13+(1 divided by 4 which is 0.25)
= 13+0.25
Which is 13.25 so your answer is 13.25, good luck hope that helps :D
