Question

3/7 : 6/12 x 4/8 ; 16/ 2

5/6 ; 10/9 + 2/3 : 4/6

Answer 1

Ai giải nhanh mình k cho

Answer 2

3/7 : 6/12 x 4/8 : 16/2

= 36/42 x 1/16

= 3/56

5/6 : 10/9 + 2/3 : 4/6

= 3/4 + 1

= 7/4

Answer 3

\(\frac{3}{7}:\frac{6}{12}\cdot\frac{4}{8}:\frac{16}{2}\)

\(=\frac{3}{7}\cdot\frac{12}{6}\cdot\frac{1}{2}\cdot\frac{2}{16}\)

\(=\frac{3}{7}\cdot2\cdot\frac{1}{2}\cdot\frac{1}{8}\)

\(=\frac{3}{7}\cdot1\cdot\frac{1}{8}\)

\(=\frac{3}{56}\)

\(\frac{5}{6}:\frac{10}{9}+\frac{2}{3}:\frac{4}{6}\)

\(=\frac{5}{6}\cdot\frac{9}{10}+\frac{2}{3}\cdot\frac{3}{2}\)

\(=\frac{3}{4}+1=\frac{7}{4}\)

Answer 4

Làm:

\(\frac{3}{7}:\frac{6}{12}\cdot\frac{4}{8}:\frac{16}{2}\)

\(=\frac{36}{42}\cdot\frac{1}{16}\)

\(=\frac{3}{56}\)

Answer 5

Làm (2):

\(\frac{5}{6}:\frac{10}{9}+\frac{2}{3}:\frac{4}{6}\)

\(=\frac{3}{4}+1\)

\(=\frac{7}{4}\)
