    a/ Ta có:

    $\frac{43}{88}$ = $\frac{43.10101}{88.10101}$=$\frac{434343}{888888}$

    b/ Ta có:

    $\frac{373373}{421421}$=$\frac{373373.1000001000000}{421.1000001000000}$

    =$\frac{373373373373373373}{421421421421421421}$

    Đáp án:

     

    Giải thích các bước giải:

     `a)` Ta có:

    `43/88` `=` `(43.10101)/(88.10101)`

    `=>` `43/88` `=` `434343/888888`

    Vậy `43/88=434343/888888`

    `b)` Ta có:

    `373373/421421` `=` `(373373.100000100000))/(421421.100000100000)`

    `=` `373373373373373373/421421421421421421`

    Vậy

    `373373/421421` `=` `373373373373373373/421421421421421421`
