[header] How to find half of any number [title] Multiply the number by 5 (five), then move it a decimal point to the left. [step] 6 (six) times 5 is 30, for instance, so put the decimal point in between the 3 and the 0. That would just be 3! [title] Divide each number by 2 if you have two even digits. <sep> (A) [step] This is the most common number you'll see. Most also start with 1, but you can add in a number to improve. (B) [step] In our example , 16 = 53. If you have two numbers, the 2 would be 7. (C) [step] Divide the digits individually, then put them together. That may make a complicated process much simpler. (D) [step] For example , 2 + 3 = 2, so don't add 2. [title] Multiply the number by 5 (6), to get 5.

Ex Output:
C

[header] How to make your cat's fur soft and shiny [title] Groom your cat to improve the look of its coat. [step] Regular brushing will remove loose hairs, dirt, and external parasites. It will also help spread natural oils produced by your cat's skin throughout its fur. <sep> (A) This will increase the overall shininess and sleekness of your cat's coat. [substeps] Brushing your cat frequently will also reduce the amount of fur that it swallows when grooming itself, thus reducing the number of hairballs it produces. (B) [substeps] Take your cat to a veterinarian or a dog groomer to have your cat's fur professionally waxed. Avoid brushing your cat's coat often to prevent it from shedding too much. (C) Be sure to do some gentle brushing prior to grooming your cat. [substeps] This is even more important if your cat has a rough coat; always use a soft bristled brush such as a slicker brush, never the broad brush as cats are susceptible to hair fractures. (D) Apply a coat removing conditioner to your cat. Then, comb or gently brush the hair to " fluff " or " disguise " the hair.
