a)x=4:7=4/7
b)x=1:2=1/2
c)???
d)x=4:9=4/9
ban oi minh xin loi nhe cau c la 1 chia X bang 3.
xin loi ban ve su sai xot nay
a,7.x=4 b,x.2=1 c,1:x d,4:x=9
=\(\frac{4}{7}\) =0,5 =2,25
hok tốt /skr
c,1:x=3
x=\(\frac{1}{3}\)
hok tốt/skr
\(a,7\times x=4\)
\(x=\frac{4}{7}\)
\(b,x\times2=1\)
\(x=\frac{1}{2}\)
\(c,1:x=\frac{1}{x}\)
\(d,4:x=9\)
\(x=\frac{4}{9}\)
*Nếu thấy đúng thì ủng hộ mk nha!!!*
Nếu sai thì mk sửa lại câu c nha
\(c,1:x=\frac{1}{3}\)
\(x=\frac{1}{3}\times1\)
\(x=\frac{1}{3}\)
* Hok tốt*
Trả lời:
\(a)\)\(7\times x=4\)
\(\Leftrightarrow x=\frac{4}{7}\)
\(b)\)\(x\times2=1\)
\(\Leftrightarrow x=\frac{1}{2}\)
\(c)\)\(\frac{1}{x}\)(Đk:\(x\ne0\))
\(d)\)\(4\div x=9\)\(\left(x\ne0\right)\)
\(\Leftrightarrow x=\frac{4}{9}\)
Hok tốt!
Vuong Dong Yet
a) \(7\times X=4\)
\(\Rightarrow X=4:7\)
\(\Rightarrow X=\frac{4}{7}\)
b) \(X\times2=1\)
\(\Rightarrow X=1:2\)
\(\Rightarrow X=\frac{1}{2}\)
c) chịu:v
d) \(4\times X=9\)
\(\Rightarrow X=9:4\)
\(\Rightarrow X=\frac{9}{4}\)
