• Can skip counting be applied with any number?
• Yes, skip-counting can be applied to any number!

You can skip-count by 5 or 10 or 2 or 4 or 7 or any whole (counting) number you can think of.
• Can you skip count by decimals? Can you skip count by fractions?
• yes you can. It is just adding.
with decimal, count by 0.05 starting at 1
1.05, 1.10. 1.15,..., 1.95, 2.00, 2.05 ...
with fraction it is a little bit more complicated, but still doable.
count by halves 1/2 starting from 3/8. to make it the addition simpler first express 1/2 in octaves. you can do that by multiplying by 4/4 since 4/4 = 1, you don't alter the value of 1/2.
1/2 x 4/4 = 4/8 skipping by halves turn into skipping by 4/8
3/8 + 4/8 = 7/8
3/8, 7/8, 11/8...
