Question

(1/5÷(2/3)+1/5)×1/3的差？

Answer 1

我们可以通过把分数转化为带分数来计算这个式子。 首先，我们将分数转化为带分数： 1/5 ÷ (2/3) = 3/5 ÷ 2/3 接着，我们可以将分数的分子分母分别相乘： 3/5 ÷ 2/3 = (3/5) * (3/2) ÷ (2/3) * (3/2) = 9/10 ÷ 6/6 最后，我们可以计算这个式子： (1/5 ÷ (2/3) + 1/5) × 1/3 = (9/10 + 1/5) × 1/3 = (9/10 + 3/15) × 1/3 = (63/50) × (3/3) ÷ (3/3) = 63/50 ÷ 3/3 = 63/50 * 3/3 = 63/50 * 3/3 = 189/150 因此，答案是189/150。

Answer 2

〔1/5÷2/3+1/5〕×1/3
=〔1/5×3/2+1/5×2/2〕×1/3
=〔1/5×（3/2+2/2）〕×1/3
=〔1/5×5/2〕×1/3
=1/2×1/3
=1/6

Answer 3

(1/5÷(2/3)+1/5)×1/3
=(1/5x3/2+1/5)×1/3
=(3/10+1/5)×1/3
=(3/10+2/10)×1/3
=5/10x1/3
=1/2x1/3
=1/6
