If a man can jump 2.45 meters and a puma can jump 1.9 TIMES higher, we know that we can simply multiply to find the answer. When something says times, that is always multiplication. So:
2.45*1.9= 4.655
4.655 is thehighest a puma can jump.
In conclusion, a puma can jump 4.655 meters and a man can jump 1.9 times less than that, or anyway you order it, it still makes sense cause it's multiplication.
The answer would be D if it was 250-6-3n. it wouldnt be A or C because 9 isnt anywhere in the problem and it wouldnt be B because she used 6 peices of paper she didnt just give it to her students
