0.07 is less than 0.1 because that is like saying 7/100 and 10/100, and 7 is less than ten.
what are the common multiples of 7 and 11 between 1 and 100
84, 91, 98, 105, 112.
There are fourteen multiples of seven that are under 100.
14 of them.
Smallest multiple of 7 greater than 100 is 15 Largest multiple of 7 less than 1000 is 142 So number of multiples of 7 = 142 - 15 + 1 = 128
70 and 75
72
there are 21 multiples.
Just 77
The multiples of 7 under 100 are :7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98. the multiples of 11 under 100 are :11, 22, 33, 44, 55, 66, 77, 88, 99
To find prime numbers less than 100, the sieve of eratosthenes filters out 1 and all multiples of 2, 3, 5, and 7. All remaining numbers less than 100 are primes.
Multiples of 7 that are less than 60 are 7, 14, 21, 28, 35, 42, 49, 56.Multiples of 14 that are less than 60 are 14, 28, 42, 56. Common multiples that are less than 60 are 14, 28, 42, and 56.
