5/12* 6/13* 26/25

giúp mình với nha đang cần gap lắm

Answer 1

=\(\frac{5x6x26}{12x13x25}=\frac{780}{3900}=\frac{1}{5}\)

Answer 2

\(\frac{5}{12}\times\frac{6}{13}\times\frac{26}{25}=\frac{5\times6\times26}{12\times13\times25}=\frac{780}{3900}=\frac{1}{5}\)

Answer 3

\(=\frac{5\cdot6\cdot26}{12\cdot13\cdot25}\)

\(=\frac{2}{20}\)

\(=\frac{1}{10}\)

Answer 4

\(\frac{5}{12}x\frac{6}{13}x\frac{26}{25}=\frac{5x6x26}{12x13x25}=\frac{780}{3900}=\frac{1}{5}\)

Answer 5

=5*6*26/12*13*25

=2/2*5

=1/5

Answer 6

\(\frac{5}{12}x\frac{6}{13}x\frac{26}{25}=\frac{5x6x26}{12x13x25}=\frac{5x2x3x13x2}{6x2x13x5x5}=turuttnha\)

Answer 7

\(=\frac{5\cdot6\cdot26}{12\cdot13\cdot25}=\frac{2}{10}=\frac{1}{5}\)

Answer 8
