    1. At the top of this page there is a link named "read shortcut techniques here", you might not have observed that Ramya. Just check that link, we've already updated shortcuts on factions and percentages with detailed explanations.

  9. The answer for the HCF one ( last question ) should be 1/60.
    As HCF = ( HCF of numerators/LCM of denominators).
