(a)
3.924%2A10%5E6+%2B+1.68%2A10%5E8
=3924000%2B+168000000
=171924000

(b)
%283.924%2A10%5E6%29%2F%287.3%2A10%5E-2%29
=%283.924%2A10%5E6%29%2F%287.3%2A%281%2F10%5E2%29%29
=%283924000%29%2F%287.3%2F100%29
=%283924000%2A100%29%2F7.3
=%28392400000%2A10%29%2F%287.3%2A10%29
=3924000000%2F73
=53753424+%2648%2F73
