Question

$\frac{m}{n} = \frac{4}{3 \: } \: and \: \frac{r}{t } = \frac{9}{14}$
, then find the value of
$\frac{3mr - nt}{4nt - 7mr}$

​

Answer 1

Answer:

m/n=4/3 r/t=9/14

m= 4n/3 r=9t/14

3mr-nt

4nt-7mr

= 3(4n/3)(9t/14) -nt

4nt - 7(4n/3)(9t/14)

=(4n×9t/14) -nt

4nt-(4n×3t/2)

= 18nt/7 -nt

4nt-6nt

=18nt-7nt

7

-2nt

= 11nt

7(-2)nt

=11nt/-14nt = -11/14
