2 . Grater then one is improper fraction.

Eg : 6/4 , 5/4

Now this type question ask in bank SSC and other 10th class, 8th class and other competitive exam

 

35\frac{2}{3} - 30 \frac{1}{3}+8\frac{3}{4}-5\frac{1}{4}

(35-30+8-5)/\frac{2}{3}-\frac{1}{3}+\frac{3}{4}-\frac{1}{4}

8/\frac{1}{3}+\frac{1}{2}

Now take LCM 3,2 =6

8\frac{5}{6}

 

This is a right answer and this fraction is proper fraction

In case Answer in improper fraction so used this trick

8\frac{6}{5}

 improper fraction that is lower number is lesser than upper number  and now convert in proper fraction

5 divided by 6 and 1\frac{1}{5}

8+ 1\frac{1}{5} =  9\frac{1}{5}     correct answer

 

Question 2

17\frac{3}{4}-(?)-12\frac{2}{3}=15\frac{1}{2}-30\frac{1}{3}

 

17\frac{3}{4}-12\frac{2}{3}-15\frac{1}{2}+30\frac{1}{3}-(?)

20/ \frac{3}{4}-\frac{1}{2}+\frac{1}{3}-\frac{2}{3}

20/ \frac{-1}{12}

 

improper fraction and in case result come in subtraction this is not correct answer

SO apply trick and rule

20* 12-1=239
