Verified Answer :

  1. 5/2× 2/5×=5/2×7  multiply the equation by the reciprocal of the coefficient 

    x= 5/2×7/1  reduce the numbers with 5,2. convert the expression into a fraction 

    x= 5
    ×7/2×1

    x= 35/2

    32. a= 19/6


    2 3/4a = 19 1/4               divide both sides of the equation by 1/4

    2
    ×3a=19                              calculate the product 

    6a=19                                    divide both sides by 6

    a=19/6
