Question

6/7 : 9/14 -1=? giúp mình với nha

Answer 1

\(\frac{6}{7}:\frac{9}{14}-1\)

\(=\frac{6}{7}.\frac{14}{9}-1\)

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

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

Answer 2

6/7 x 14/9 -1

84/63-63/63

21/63

Answer 3

\(\frac{6}{7}\div\frac{9}{14}-1=\frac{6}{7}\times\frac{14}{9}-\frac{3}{3}\)

\(=\frac{6.14}{7.9}-\frac{3}{3}\)

\(=\frac{4}{3}-\frac{3}{3}\)

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