Because 10 is a factor of 100.
There are an infinite number of multiples of 100. 100, 200, 300,400, ....
Numbers from 0 to 100 that are multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. That's ten numbers, so the fraction of numbers from 1 to 100 that are multiples of 10 is 10/100. In simplest form it is 1/10.
Since 10 is a multiple of 5, all multiples of 10 are multiples of 5.
Oh, dude, let me break it down for you. So, the factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Out of these, the multiples of 5 are 5, 10, 20, 25, 50, and 100. That's like 6 factors of 100 that are multiples of 5. Easy peasy, lemon squeezy!
80 and 100
Yes.
50 is a factor of all the multiples of 50: 50, 100, 150, 200, etc.
10, 15, 35, and 100 are all multiples of 5.
There are an infinite number of multiples of 100. 100, 200, 300,400, ....
Prefix hecto is used to denote multiples of meter and uses factor 102 (100). 10 meters = 10 / 102 = 10 / 100 = 0.1 hectometer
Not AllTo find out if all numbers that have 5 as a factor have 2 as a factor, you can list the multiples of each. 5's multiples are 5, 10, 15, 20...2's multiples are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20...5 and 15 are multiples of 5, but not 2, so all numbers that have 5 as a factor DO NOT have 2 as a factor.It is not really necessary to write that all out because the fact that 5 is an odd number and 2 is only a factor of even numbers indicates that all numbers that have 5 as a factor would not have 2 as a factor. Only the multiples of 5 that are even have 2 as a factor also.
15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,72,75,78,81,84,87,90,93,96,99
5, 10, and 20 are all multiples of 5 and factors of 20.
I presume you mean what are all the multiples of 9 up to 100 (and not what are all the multiples of 9, 10, 11, ..., 100 of which there are infinitely many): 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.
90 that is all
Just 90.
100
