Answer 1

`3-4/5:1/3`

`=3-4/5xx3/1`

`=3-12/5`

`=15/5-12/5`

`=3/5`

 

`5/9xx2/7-3/7`

`=10/63-3/7`

`=10/63-27/63`

`=-17/63`

 

`12/8-3/4+3`

`=12/8-6/8+24/8`

`=30/8=15/4`

Answer 2

$3-4/5:1/3$

 

=3−4/5��3/1$=3-4/5xx3/1$

 

=3−12/5$=3-12/5$

 

=15/5−12/5$=15/5-12/5$

 

=3/5$=3/5$

 

5/9��2/7−3/7$5/9xx2/7-3/7$

 

=10/63−3/7$=10/63-3/7$

 

=10/63−27/63$=10/63-27/63$

 

=−17/63$=-17/63$

 

12/8−3/4+3$12/8-3/4+3$

 

=12/8−6/8+24/8$=12/8-6/8+24/8$

 

=30/8=15/4$=30/8=15/4$

 

 

Answer 3

$3-4/5:1/3$

 

=3−4/5��3/1$=3-4/5xx3/1$

 

=3−12/5$=3-12/5$

 

=15/5−12/5$=15/5-12/5$

 

=3/5$=3/5$

 

5/9��2/7−3/7$5/9xx2/7-3/7$

 

=10/63−3/7$=10/63-3/7$

 

=10/63−27/63$=10/63-27/63$

 

=−17/63$=-17/63$

 

12/8−3/4+3$12/8-3/4+3$

 

=12/8−6/8+24/8$=12/8-6/8+24/8$

 

=30/8=15/4$=30/8=15/4$

 

 

Answer 4

$3-4/5:1/3$

 

=3−4/5��3/1$=3-4/5xx3/1$

 

=3−12/5$=3-12/5$

 

=15/5−12/5$=15/5-12/5$

 

=3/5$=3/5$

 

5/9��2/7−3/7$5/9xx2/7-3/7$

 

=10/63−3/7$=10/63-3/7$

 

=10/63−27/63$=10/63-27/63$

 

=−17/63$=-17/63$

 

12/8−3/4+3$12/8-3/4+3$

 

=12/8−6/8+24/8$=12/8-6/8+24/8$

 

=30/8=15/4$=30/8=15/4$

 

 

Answer 5

\(3-\dfrac{4}{7}:\dfrac{1}{3}\)

\(=3-\dfrac{4}{7}.\dfrac{3}{1}\)

\(=3-\dfrac{12}{5}\)

\(=\dfrac{15}{5}-\dfrac{12}{5}\)

\(=\dfrac{3}{5}\)

________________________________________

\(\dfrac{5}{9}.\dfrac{2}{7}-\dfrac{3}{7}\)

\(=\dfrac{10}{63}-\dfrac{3}{7}\)

\(=\dfrac{10}{63}-\dfrac{27}{63}\)

\(=\dfrac{-17}{63}\)

________________________________________

\(\dfrac{12}{8}-\dfrac{3}{4}+3\)

\(=\dfrac{12}{8}-\dfrac{6}{8}+\dfrac{24}{8}\)

\(=\dfrac{30}{8}=\dfrac{15}{4}\)
