    .5406 = 5406/10000
    count the number of zeros in the denominator, and count the number of digits past the decimals, they are the same
    5406/10000
    = 2703/5000 ---- divided top and bottom by 2 to reduce , 2 being the HCF

    do the others the same
    careful in #3

    3.
    3.274 = 3274/1000 ---- again, notice the number of zeros on the bottom match the number of decimals in the original
    = .....
