\(x-\dfrac{5}{7}=\dfrac{3}{5}.\dfrac{1}{2}\)
\(x-\dfrac{5}{7}=\dfrac{3}{10}\)
\(x=\dfrac{3}{10}+\dfrac{5}{7}=\dfrac{71}{70}\)
\(x-\dfrac{5}{7}=\dfrac{3}{5}\times\dfrac{1}{2}\)
\(x-\dfrac{5}{7}=\dfrac{3}{10}\)
\(x=\dfrac{3}{10}+\dfrac{5}{7}\)
\(x=\dfrac{71}{10}\)
X-5/7=3/5 x 1/2
x - 5/7 = 3/10
x = 3/10 +5/7
x = 71/70
x - 5/7 = 3/5 x 1/2
x - 5/7 = 3/10
x = 3/10 + 5/7
x = 71/70
vậy x =...
\(=>x=\left(\dfrac{3}{5}\times\dfrac{1}{2}\right)+\dfrac{5}{7}=\dfrac{3}{10}+\dfrac{5}{7}=\dfrac{71}{70}\)
X-5/7=3/5 NHÂN 1/2
X-5/7 = 3/10
X = 3/10 + 5/7
X = 71/70
Đáp án:
X-5/7=3/5 x 1/2
x - 5/7 = 3/10
x = 3/10 +5/7
x = 71/70
x - 5/7 = 3/10
x = 3/10 + 5/7
x = 26/70
