Question

How to solve these problems

Answer 1

Answer:

$\frac{\frac{14}{7}\cdot \:3+9}{9\left(\frac{18}{6}\div \frac{21}{3}\right)}$

$\frac{14}{7} =2\\=2\cdot \:3+9$

$=6+9$

$=15$

$9\left(\frac{18}{6}\div \frac{21}{3}\right)$

$\frac{18}{6} =3$

$\frac{21}{3} =7$

$9(3\div 7)=\frac{3}{7}$

$=9\cdot \frac{3}{7}=\frac{27}{7}$

$\frac{27}{7} =3\frac{6}{7}$

$=\frac{15}{3\frac{6}{7}}$

-------------

$\frac{31}{\:7}+\frac{28}{13}$

$LCM\: of \: 7 \:and \: 13 :91$

$=\frac{403}{91}+\frac{196}{91}$

$=\frac{403+196}{91}$

$=\frac{599}{91}$

--------------

$-3-21\cdot \frac{66}{22}$

$\frac{66}{22} =3$

$=-3-21\cdot \:3$

$21\cdot \:3=63$

$=-3-63$

$=-66$
