Question

8．$\begin{array}{l}\frac{3}{4}\end{array}$+$\begin{array}{l}\frac{3}{4}\end{array}$+$\begin{array}{l}\frac{3}{4}\end{array}$+$\begin{array}{l}\frac{3}{4}\end{array}$改寫成乘法算式是$\begin{array}{l}\frac{3}{4}\end{array}$×4．

Answer 1

分析 分?jǐn)?shù)乘整數(shù)的意義與整數(shù)乘法的意義相同，就是求幾個(gè)相同加數(shù)和的簡(jiǎn)便運(yùn)算；據(jù)此解答．

解答 解：$\begin{array}{l}\frac{3}{4}\end{array}$+$\begin{array}{l}\frac{3}{4}\end{array}$+$\begin{array}{l}\frac{3}{4}\end{array}$+$\begin{array}{l}\frac{3}{4}\end{array}$=$\begin{array}{l}\frac{3}{4}\end{array}$×4，
故答案為：$\begin{array}{l}\frac{3}{4}\end{array}$×4．

點(diǎn)評(píng) 此題考查了分?jǐn)?shù)乘整數(shù)意義的運(yùn)用．
