    $\text{ 5,28 × ( 1,62 + 2,38 ) – 0,76 }$
    $\text{ = 5,28 × 4 – 0,76 }$
    $\text{ = 21,12 – 0,76 }$
    $\text{ = 20,36 }$
    $\text{ ____________________ }$
    $\text{ y : 5,8 = 6,45 + 3,55 }$
    $\text{ y : 5,8 = 10 }$
    $\text{ y = 10 × 5,8 }$
    $\text{ y = 58 }$

    5,28 × ( 1,62 + 2,38 ) – 0,76
    = 5,28 × 4 – 0,76
    = 21,12 – 0,76
    = 20,36
    y : 5,8 = 6,45 + 3,55
    y : 5,8 = 10 y = 10 × 5,8
    y = 58
