To find this you multiply the 2 numbers together. 3*3/4=2.25.
2.25 in fraction form is
The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.
The total speed is (120 mi)/(3 h) = 40 mi/h.
The speed ratio is ...
... Bill : Joe = 3 : 1
so the speed ratio Bill : Total is ...
... 3 : (3+1) = 3:4.
Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
It is a right Right Triangle because, they have two equal sides.
7^5/4 would be the answer to the question I think you are asking
