An infinite number of ways.
.1+.9, .2+.8, .3+.7, .4+.6
then, .01+.99, .02+.98, .03+.97, ....
then, .001+.999, .002+.998
Then there are multiples:
1*1, 2*.5, etc
And that is only using binary operations. You could have .1+.1+.8, .1+.2+.7 (ternary operations), as well

To find out how many 5s make 100, you divide 100 by 5. This calculation shows that 100 ÷ 5 = 20. Therefore, it takes 20 fives to make 100.
293 ways
With whole numbers, there are five ways.
There are infinitely many ways to get to 100.

There are many ways to make the number 50 by combining different numbers through addition, subtraction, multiplication, and division. Some examples include 25+25, 100-50, 10*5, and 100/2. The total number of ways to make 50 depends on the range of numbers and operations allowed in the calculation.
There are many. Various ways to make a dollar using coins. 100 pennies, 4 quarters, 2 50 cent coins, 1 50 cent coin and 2 quarters, 10 dimes, 20 nickels, and many variations. There are 293 ways to make a dollar but maybe there are more possible ways.
