Answer :
a)Ken jumps further than Steve.
b)Ken jumps further than Steve by 0.3 meters.
Compared to Steve who jumped 1.2 meters, Ken jumped 1 1/2 meters, which can be expressed as 3/2 meters or 1.5 meters. Therefore, Ken jumped further than Steve.
To find out how much further Ken jumped, we need to subtract Steve's jump distance from Ken's jump distance. Ken jumped 1.5 meters and Steve jumped 1.2 meters, so the difference is 1.5 - 1.2 = 0.3 meters.
Therefore, Ken jumps 0.3 meters further than Steve.
