7/4 - x . 5/6 = 1/2 + 1/3
7/4 - x . 5/6 = 5/6
7/4 - x = 5/6 : 5/6
7/4 - x = 1
x = 7/4 - 1
x = 3/4
7/4 - x . 5/6 = 1/2 + 1/3
7/4 - x . 5/6 = 5/6
7/4 - x = 5/6 : 5/6
7/4 - x = 1
x = 7/4 - 1
x = 3/4
7-4-Xx5/6 = 5/6
x5/6 = 7/4 - 5/6
x5/6 = 11/12
x = 11/12 : 5/6
x = 11/10
cho mình hỏi có phải là 7/4 - nhân x nhân 5/6 = 1/2 = 1/3
đúng k
\(\frac{7}{4}\)-X x \(\frac{5}{6}\)=\(\frac{3}{6}\)+ \(\frac{2}{6}\)
\(\frac{7}{4}\)-X x \(\frac{5}{6}\)=\(\frac{5}{6}\)
\(\frac{7}{4}\)- X = \(\frac{5}{6}\):\(\frac{5}{6}\)
\(\frac{7}{4}\)- X =1
X=\(\frac{7}{4}\)-1
X=\(\frac{3}{4}\)
tk nhé@@@@@@@@@@@@
7/4-(Xx5/6)=3/6+2/6
7/4-(Xx5/6)=5/6
(Xx5/6)=7/4-5/6
(Xx5/6)=42/24-20/24
(Xx5/6)=22/24
X=22/24:5/6
X=22/24x6/5
X=22/20
X=11/10
\(\frac{7}{4}\)- X x \(\frac{5}{6}\)= \(\frac{1}{2}\)+ \(\frac{1}{3}\)= \(\frac{5}{6}\)
\(\frac{7}{4}\) - \(\frac{5}{6}\)= X x \(\frac{5}{6}\)
\(\frac{11}{12}\)= X x \(\frac{5}{6}\)
X = \(\frac{11}{12}\)x \(\frac{6}{5}\)
X = \(\frac{11}{10}\)
