So the right answer is none.
both are multiples of 23, so the fraction will be 17/19
So the right answer is none.
Question 4 
If P = [(7/9 â€“ 3^{7}/_{9}) / 4^{1}/_{5}] + [{1/2(3^{1}/_{2})} / (5^{9}/_{3 }â€“ 8^{5}/_{9})] then what will be the value of P
140^{3}/_{121}  
3^{121}/_{140}  
0  
none 
Question 4 Explanation:
Just solve the question using the BODMAS rule and you will get B as the correct answer.
Question 5 
If P = [{1/2/ (Â¼ 1/2 1/2)}] x [(4/5)/(2^{1}/_{2} + 3^{1}/_{2})]  21 then what we can say for P
P will be a proper fraction  
P will be a Improper fraction  
P will be a negative improper fraction  
None 
Question 5 Explanation:
[{1/2/ (Â¼ 1/2 1/2)}] = (Â½)/(3/4)= 2/3
[(4/5)/(2^{1}/_{2} + 3^{1}/_{2})]
= (4/5)/(5/7 +7/2)
= (4/5) / 6 =2/15
So Â 2/3 x 2/15 = 4/45
AndÂ 4/45 21 = 949/45
So the best answer to this problem is Option C
[(4/5)/(2^{1}/_{2} + 3^{1}/_{2})]
= (4/5)/(5/7 +7/2)
= (4/5) / 6 =2/15
So Â 2/3 x 2/15 = 4/45
AndÂ 4/45 21 = 949/45
So the best answer to this problem is Option C
