  1. Giải đáp + Lời giải và giải thích chi tiết:
    $\dfrac14+\dfrac1{12}+\dfrac{12}{25}+\dfrac{75}{100}+\dfrac5{12}+\dfrac{13}{15}\\=\dfrac14+\dfrac1{12}+\dfrac{12}{25}+\dfrac{3}{4}+\dfrac5{12}+\dfrac{13}{15}\\=1+\dfrac12+\dfrac{127}{75}\\=1+\dfrac{75}{150}+\dfrac{254}{150}\\=1+\dfrac{329}{150}=\dfrac{479}{150}$

  2. Giải đáp+Lời giải và giải thích chi tiết:
     1/4+1/12+12/25+75/100+5/12+13/15
    = 1/4+1/12+12/25+75/100+5/12+13/15
    = (1/4+3/4)+(1/12+5/12)+ 12/25+13/15
    = 1 + 1/2 + 12/25+13/15
    = 3/2 + 101/75
    = 427/150
