1/6:x= 1/4+3/8=5/8
=> x= 1/6 : 5/8
=> x=4/15
1/6:x=1/4+3/8
1/6:x=5/8
x=1/6:5/8
x=2/15
nha ban Nguyễn Duy Tân
1/6 : x - 3/8 = 1/4
=> 1/6 : x = 1/4 + 3/8
1/6 : x = 5/8
=> x = 1/6 : 5/8
x = 4/15
1/6:x-3/8=1/4
=>1/6:x=1/4+3/8=5/8
=>x=1/6:5/8=4/15
Tớ không hiểu nên tớ có 2 trường hợp, trường hợp nào đúng với đề bài cậu chọn nhé!
Trường hợp 1:
\(\frac{1}{6}:x-\frac{3}{8}=\frac{1}{4}\)
\(\Rightarrow\frac{1}{6}:x=\frac{1}{4}+\frac{3}{8}\)
\(\Rightarrow x=\frac{1}{6}:\frac{5}{8}\)
\(\Rightarrow x=\frac{4}{15}\)
Trường hợp 2:
\(\frac{1}{6:x}-\frac{3}{8}=\frac{1}{4}\)
\(\Rightarrow\frac{1}{6:x}=\frac{1}{4}+\frac{3}{8}\)
\(\Rightarrow6:x=1:\frac{5}{8}\)
\(\Rightarrow x=6:\frac{8}{5}\)
\(\Rightarrow x=\frac{15}{4}\)
1/6:x-3/8=1/4
1/6:x =1/4+3/8
1/6:x =5/8
x =1/6:5/8
x =8/30=4/15
k nha các bạn !!
1/6:x-3/8=1/4
1/6:x=1/4+3/8
1/6:x=5/8
x=1/6:5/8
x=1/6.8/5
x=4/15
