Question

23/6 :x - 2/5 = 1/4

Answer 1

23/6  :x - 2/5 = 1/4

23/6 : x = 13/20

x = 23/6 . 20/13

x = 230/39

Answer 2

x=230/39

Answer 3

\(\frac{23}{6}:x=\frac{1}{4}+\frac{2}{5}\)

\(\frac{23}{6}:x=\frac{5}{20}+\frac{8}{20}\)

\(\frac{23}{6}:x=\frac{13}{20}\)

\(x=\frac{23}{6}:\frac{13}{20}\)

\(x=\frac{23x20}{13x6}\)

\(x=5\frac{35}{39}\)

Answer 4

23/6:x=1/4+2/5

23/6:x=13/20

x=23/6:13/20

x=23/6.20/13

x=115/17

Vậy x=115/17

Answer 5

\(\frac{23}{6}:x=\frac{1}{4}+\frac{2}{5}\)

\(\frac{23}{6}:x=\frac{13}{20}\)

\(x=\frac{13}{20}:\frac{23}{6}\)

\(x=\frac{39}{230}\)

Answer 6

\(\frac{23}{6}:x-\frac{2}{5}=\frac{1}{4}\)

\(\frac{23}{6}:x=\frac{1}{4}+\frac{2}{5}\)

\(\frac{23}{6}:x=\frac{5}{20}+\frac{8}{20}\)

\(\frac{23}{6}:x=\frac{13}{20}\)

\(x=\frac{23}{6}:\frac{13}{20}\)

\(x=\frac{23}{6}x\frac{20}{13}=\frac{230}{39}\)
