6/x = 4/6 ; 6/x giữ nguyên 4/6 = 2/3 = 6/9 => x= 9
x/72 = 10/16 ; 10/16 = 5/8 = 45/72 => x = 45
x + 1/6 = 2/3 x = 2/3 - 1/6 = 1/2 => x = 1/2
x - 2/12 = 3/4 x = 3/4 + 2/12 = 11/12
a x * 4 + [1/2 + 1/4 + 1/8 + 1/6] = 23/16
x * 4 + 25/24 = 23/16
x * 4 = 23/16 - 25/24
x * 4 = 38/96 = 19/48
x = 19/48 / 4
x = 19/172
b x * 1 = 425
x = 425 / 1
x = 425
\(x\times16+54\times x=700=>\left(16+54\right)\times x=700\)
\(70\times x=700=>x=700:70=10\)
đúng nha
\(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=\frac{23}{16}\)
\(4x+\frac{15}{16}=\frac{23}{16}\)
\(4x=\frac{1}{2}\)
\(x=\frac{1}{8}\)
Vậy \(x=\frac{1}{8}\)
\(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=\frac{23}{16}\)
\(\Rightarrow\left(x+x+x+x+x\right)+\left(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\right)=\frac{23}{16}\)
\(\Rightarrow5x+\frac{15}{32}=\frac{23}{16}\)
\(\Rightarrow5x=\frac{23}{16}-\frac{15}{32}\)
\(\Rightarrow5x=\frac{31}{32}\)
\(\Rightarrow x=\frac{31}{32}.\frac{1}{5}=\frac{31}{160}\)
(14 x 14 - X - 16) : 4 =148 : 4
(14 x 14 - 16- X) : 4 = 37
( 180 - X ) : 4 =37
180 - X =37 x 4
180 - X =148
X =180 - 148
X =32
(14 x14- X-16):4=148:4
14 x14 -X-16=148
196-X-16 =148
180-X =148
X=180-148
x=32
6+x-16
=6+16-16
=22-16
=6
6+x-16
=6+16-16
=22-16
=6
