X x 5/8 = 15 - 1/2
mik chọn ba bạn nhanh nhất nha , nhớ ghi đủ chi tiết nha

Answer 1

x x\(\frac{5}{8}\)= 15 -\(\frac{1}{2}\)

x x\(\frac{5}{8}\)=\(\frac{29}{2}\)

          x =\(\frac{29}{2}\):\(\frac{5}{8}\)

          x =\(\frac{116}{5}\)

Chúc bạn học tốt.

😁😁😁

Answer 2

\(x\times\frac{5}{8}=15-\frac{1}{2}\)

\(x\times\frac{5}{8}=14\)

\(x=14:\frac{5}{8}\)

\(x=\frac{112}{5}\)

Answer 3

\(x\times\frac{5}{8}=15-\frac{1}{2}\)

\(\Leftrightarrow x\times\frac{5}{8}=\frac{30}{2}-\frac{1}{2}\)

\(x\times\frac{5}{8}=\frac{29}{2}\)

\(x=\frac{29}{2}\div\frac{5}{8}\)

\(\Leftrightarrow x=\frac{29}{2}\times\frac{8}{5}\)

\(x=\frac{232}{10}\)

\(\Leftrightarrow x=\frac{116}{5}\)
