你能將下面的加法改為乘法嗎?
0.1+0.1+0.1+0.1+0.1=________×________
0.5+0.5+0.5=________×________
0.3+0.3+0.3+0.3+0.3+0.3=________×________
0.6+0.6+0.6+0.6=________×________.
0.1 5 0.5 3 0.3 6 0.6 4
分析:根據(jù)小數(shù)乘法的意義,求幾個相同加數(shù)和的簡便運算用乘法.
解答:0.1+0.1+0.1+0.1+0.1=0.1×5,
0.5+0.5+0.5=0.5×3,
0.3+0.3+0.3+0.3+0.3+0.3=0.3×6,
0.6+0.6+0.6+0.6=0.6×4.
故答案為:0.1,5,0.5,3,0.3,6,0.6,4.
點評:此題考查了小數(shù)乘法的意義及運用.
