Question
choose the sum that is less than 4.
$3\frac{2}{5} + \frac{1}{5}$
find the sum. write your answer as a mixed number.
$3\frac{2}{5} + \frac{1}{5} = \square \frac{?}{?}$
Step1: 计算分数部分
同分母分数相加,分母不变,分子相加,即\(\frac{2}{5} + \frac{1}{5} = \frac{2 + 1}{5} = \frac{3}{5}\)。
Step2: 合并整数部分和分数部分
整数部分为\(3\),加上分数部分\(\frac{3}{5}\),得到\(3\frac{3}{5}\)。
