Question

Tìm x thỏa mãn;

\(y:2\frac{1}{2}=1\frac{3}{4}:2\frac{1}{3}\)

Answer 1

\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)

\(y:\frac{5}{2}=\frac{3}{4}\)

\(y=\frac{3}{4}.\frac{5}{2}\)

\(y=\frac{15}{8}\)

Vậy \(y=\frac{15}{8}\)

Chúc bạn zui ~^^

Answer 2

\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)

\(y:\frac{5}{2}=\frac{3}{4}\)

\(y=\frac{3}{4}\cdot\frac{5}{2}\)

\(y=1.875\)

Vậy y = 1.875

Answer 3

Theo bài ra,ta có:

\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)

=>\(y\cdot\frac{2}{5}=\frac{7}{4}\cdot\frac{3}{4}\)

=>\(y=\frac{3}{4}:\frac{2}{5}=\frac{3}{4}\cdot\frac{5}{2}=\frac{3\cdot5}{4\cdot2}=\frac{15}{8}\)

Vậy y=15/8

Answer 4

\(y:2\frac{1}{2}=1\frac{3}{4}:2\frac{1}{3}\)

\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)

\(y:\frac{5}{2}=\frac{3}{4}\)

\(y=\frac{3}{4}.\frac{5}{2}\)

\(y=\frac{15}{8}\)
