异分母分数加法
Adding fractions (different denominators)
通过找公分母,对分母是同一个数的倍数的分数进行加法和减法运算。
Add and subtract fractions with denominators that are multiples of the same number by finding a common denominator
学习证据 / Evidence
- 通过通分成分母为 6 的分数来计算 1/3 + 1/6:2/6 + 1/6 = 3/6 = 1/2
- 通过通分成分母为 8 的分数来计算 3/4 − 1/8
- 计算 2/5 + 3/10 并化简答案
- Calculate 1/3 + 1/6 by converting to sixths: 2/6 + 1/6 = 3/6 = 1/2
- Calculate 3/4 − 1/8 by converting to eighths
- Add 2/5 + 3/10 and simplify the answer
