Answer:
- Leroy Sands & Walt Smith - green
- Frank Cook & Phil Hawley - yellow
- Paul O'Brien & Alan Wilson - blue
- Henry Gladstone & Don Hughes - red
Step-by-step explanation:
First of all, it is convenient to choose the false statement.
We note that statements 7 (Alan is first) and 10 (Alan did not finish) are contradictory, so one of them must be false. Statement 5 has Henry & Hughes together, so is not consistent with statement 7 (Alan & Hughes). So, statement 7 is inconsistent with two other statements, thus must be the false one.

The attached table shows how we parsed the statements. An "O" signifies a combination that must occur; and "X" signifies one that cannot occur. We have used "-" to fill the spaces that are inconsistent with the locations of "O". The red letters are deduced from the others.
The first complete set we found was Henry & Hughes (Don & Gladstone) who were in the (red) capsized raft and did not finish. The second complete set we found was Phil & Cook (Frank & Hawley) who were in the (yellow) raft that finished second. We know Paul & Wilson (Alan & Partner) finished last, so Phil & Cook could not have been Paul and Wilson. Finally, O'Brien and Leroy were not on the same boat, so Paul must be Paul O'Brien and Leroy must be Leroy Sands.
Answer:
Yes
Step-by-step explanation:
3 medium cars to 1 small car can be made into a fraction like this: or
. But you must be consistent if the denominator represents medium cars or small cars.
For this, I'm just going to make medium cars the numerator.
18 medium cars to 6 cars can be made into a fraction like this : .
When you divide both fractions in a calculator (or in your head), you will realize that they both are the same value (equivalent).
These ratios are equivalent.
