    Solution


    20      12
    ---- - ----
    7      7


    20/7 sticks means 20 pieces of sticks of 1/7 size.
    12/7 sticks means 12 pieces of sticks of 1/7 size.

    As both the denominators are equal, So we can subtract them easily.

    In first case, there are 20 such smaller pieces
    And in the second case, there are 12 such smaller pieces.

    So the total number of pieces are 20 - 12 = 8.

    And in both cases, the smallest pieces of the sticks are of 1/7 size.

    So there are total 8 pieces of stick of 1/7 size,
    which gives 8/7 sticks.



    20/7 छड़ी का मतलब है, 20 टुकड़ों की छड़ी 1/7 आकार की ।
    12/7 छड़ी का मतलब है, 12 टुकड़ों की छड़ी 1/7 आकार की ।

    चूंकि दोनों हर(denominator) समान हैं, तो हम उन्हें आसानी से घटा सकते हैं।

    पहले मामले में, ऐसे 20 छोटे टुकड़े हैं
    और दूसरे मामले में, ऐसे 12 छोटे टुकड़े हैं

    तो टुकड़ों की कुल संख्या 20 - 12 = 8 हैं।

    अब दोनों मामलों में स्टिक का सबसे छोटा टुकड़ा 1/7 है

    तो 1/7 आकार की छड़ी के कुल 8 टुकड़े हैं,
    जो 8/7 स्टिक देता है।
