Hi ninadbe;

You can do #8 in about 30 seconds like this:

10% of 550 = 55
1 / 4 of 55 = 13.75

550 - 55 = 495 + 13.75 = 508.75

3) (135/15)(135/45)(32/24) = (9)(3)(4/3) = 36.

8) ((92.5)/100)(1100/2) = (92.5)(1/2)(11) = 462.5 + 46.25 = 508.75. The sum is equivalent to the usual "trick" for finding 46.25 11.
