My pet frog jumps $$3\text{m}$$ per jump. If it wants to jump from one end of a $$100\text{m}$$ field to another, the least number of jumps it will take is．

Since $$100\div 3=33$$ with remainder $$1$$, it takes my frog $$33$$ jumps to jump $$99\text{m}$$. It needs $$1$$ more jump, for $$34$$ jumps in all, to go at least $$100\text{m}$$.
