Question

1\(\frac{1}{3}\): ( 1\(\frac{2}{3}\)- x ) = \(\frac{8}{7}\)

Bài 2 :

Xếp theo thứ tự tăng dần : 7 ; \(\frac{75}{100}\) ; 6,04 ; 4\(\frac{1}{2}\)

Answer 1

\(1\frac{1}{3}:\left(1\frac{2}{3}-x\right)=\frac{8}{7}\)

\(\frac{4}{3}:\left(\frac{5}{3}-x\right)=\frac{8}{7}\)

\(\left(\frac{5}{3}-x\right)=\frac{4}{3}:\frac{8}{7}\)

\(\left(\frac{5}{3}-x\right)=\frac{7}{6}\)

\(x=\frac{5}{3}-\frac{7}{6}\)

\(x=\frac{1}{2}\)

Bài 2:

            theo thứ tự tăng dần:  \(\frac{75}{100};\)\(4\frac{1}{2};\)\(6,04;\)\(7.\)

Answer 2

\(1\frac{1}{3}:\left(1\frac{2}{3}-x\right)=\frac{8}{7}\Rightarrow\frac{4}{3}:\left(\frac{5}{3}-x\right)=\frac{8}{7}\)

\(\Rightarrow\frac{5}{3}-x=\frac{4}{3}:\frac{8}{7}\Rightarrow\frac{5}{3}-x=\frac{7}{6}\)

\(\Rightarrow x=\frac{5}{3}-\frac{7}{6}\Rightarrow x=\frac{1}{2}\)

Answer 3

bài 2

\(\frac{75}{100}=\frac{3}{4}=0,75;4\frac{1}{2}=\frac{9}{2}=4,5\)

sắp xếp:\(\frac{75}{100};4\frac{1}{2};6.04;7\)
