Answer 1

Answer:

$\huge\boxed{\fcolorbox{red}{blue}{Answer}}$

Ans.First take l.c.m.of denominator(7,11) i.e 77

Now,same the denominator with L.C.M.

$\frac{43}{7} ×\frac{11}{11} =473/77\\</p><p>\frac{31}{11} ×\frac{7}{7} =217/77$

Now,Solve the equation;

473/77-217/77

=>(473-217)/77

=>256/77

3Ans.First take l.c.m.of denominator(10,80) i.e 80

Now,same the denominator with L.C.M.

$\frac{63}{80} ×\frac{1}{1} =63/80\\</p><p>\frac{9}{10} ×\frac{8}{8} =72/80$

Now,Solve the equation;

63/80+72/80

=>63+72/80

=>125/80

=>25/16

=>1 whole 9/16

Answer 2
