  • Bonjour

    A = 24/30 -4/30 + 1/30 = 21/30 = 7/10

    B= 24/20 - 2/20 = 22/20 = 11/10

    ( priorité à la multiplication)

    C= 24/64 -8/64 +1/64 = 17/64

  • A=4/5-2/15+1/30

    =(24-4+1)/30

    =21/30

    =(21÷3)/(30÷3)

    =7/10

    B=6/5-2/5×1/4

    =6/5-(2×1)/(5×4)

    =6/5-2/20

    =6/5-(2÷2)/(20÷2)

    =6/5-1/10

    =(12-1)/10

    =11/10

    C=3/8-2/16+1/64

    =(24-8+1)/64

    =17/64
