19/17 | |

23/19 | |

39/17 | |

none |

Question 3 Explanation:

Just divide the 391 from 437;

both are multiples of 23, so the fraction will be 17/19

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 PP 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

= (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
