Question

Giúp tớ giải bài toán này với:

7/3:0,2x=7/6:0,8

Answer 1

\(\dfrac{7}{3}:0,2x=\dfrac{7}{6}:0,8\)

⇔ \(\dfrac{7}{3}:0,2x=\dfrac{35}{24}\)

⇔ \(0,2x=\dfrac{7}{3}:\dfrac{35}{24}\)

⇔ 0,2x = 1,6

⇔ x = 1,6 : 0,2

⇔ x = 8

Vậy x = 8

Answer 2

\(\dfrac{7}{3}:0,2x=\dfrac{7}{6}:0,8\)
\(\dfrac{7}{3}:\dfrac{2}{10}x=\dfrac{7}{6}:\dfrac{8}{10}\)
\(\dfrac{7}{3}:\dfrac{1}{5}x=\dfrac{7}{6}:\dfrac{4}{5}\)
\(\dfrac{7}{3}:\dfrac{1}{5}x=\dfrac{7}{6}.\dfrac{5}{4}\)
\(\dfrac{7}{3}:\dfrac{1}{5}x=\dfrac{35}{24}\)
\(\dfrac{1}{5}x=\dfrac{7}{3}:\dfrac{35}{24}\)
\(\dfrac{1}{5}x=\dfrac{7}{3}.\dfrac{24}{35}\)
\(\dfrac{1}{5}x=\dfrac{8}{5}\)
\(x=\dfrac{8}{5}:\dfrac{1}{5}\)
\(x=\dfrac{8}{5}.5\)
\(x=8\)
Vậy \(x=8\)

Answer 3

$\frac{}{}:0,2x=\frac{7}{6}:0,8$
$\frac{7}{3}:\frac{2}{10}x=\frac{7}{6}:\frac{8}{10}$
$\frac{7}{3}:\frac{1}{5}x=\frac{7}{6}:\frac{4}{5}$
$\frac{7}{3}:\frac{1}{5}x=\frac{7}{6}.\frac{5}{4}$
$\frac{7}{3}:\frac{1}{5}x=\frac{35}{24}$
$\frac{1}{5}x=\frac{7}{3}:\frac{35}{24}$
$\frac{1}{5}x=\frac{7}{3}.\frac{24}{35}$
$\frac{1}{5}x=\frac{8}{5}$
$x=\frac{8}{5}:\frac{1}{5}$
$x=\frac{8}{5}.5$
$x=8$
Vậy $x=8$

Answer 4

hơi lệch 1 tí nha

Thông cảm!

Answer 5

Sai hết rồi kết quả bằng 1/8

Answer 6

\(\dfrac{7}{3}:0,2x=\dfrac{7}{6}:0,8\)

\(\dfrac{7}{3}.5x=\dfrac{7}{6}.\dfrac{5}{4}\)

\(\dfrac{7}{3}.5x=\dfrac{35}{24}\)

\(5x=\dfrac{35}{24}:\dfrac{7}{3}\)

\(5x=\dfrac{35}{24}.\dfrac{3}{7}\)

\(5x=\dfrac{5}{8}\)

\(x=\dfrac{5}{8}:5\)

\(x=\dfrac{5}{8}.\dfrac{1}{5}\)

\(x=\dfrac{1}{8}\)

vậy \(x=\dfrac{1}{8}\)

Answer 7

ghi vào máy tính \(\dfrac{7}{3}:0,2.x=\dfrac{7}{6}:0,8\) (dấu . có nghĩa là dấu nhân)

sau đó nhấn SHIFT+CALC tiếp theo đó nháy dấu =
