A negative number is defined as a number that is less than zero. Positive numbers, on the other hand, are more than zero. You can see that positive numbers are greater than negative numbers because they are all above zero, which negative numbers are not.
Numbers greater than 1 have reciprocals less than 1. Numbers less than 1 have reciprocals greater than 1.

130 numbers
There are 90 integers less than 1,000 that are divisible by 11.
There are 130 positive integers less than 1,000 that are divisible by seven but not divisible by 11
1000 ÷ 8 = 125 → largest less than 1000 divisible by 8 is 124 x 8 = 992

8 of the numbers less than 660 are divisible by 5 and 11 but not 3. All numbers divisible by 5 and 11 are multiples of their lcm; lcm(5, 11) = 55 All numbers divisibile by 5, 11 and 3 are multiples of their lcm; lcm(5, 11, 3) = 165 659 ÷ 55 = 11 54/55 → 11 numbers less than 660 are divisible by 5 and 11 659 ÷ 165 = 3 164/165 → 3 numbers less than 660 are divisible by 5, 11 and 3 → of the 11 numbers less than 660 divisible by 5 and 11, 3 are also divisible by 3 → 11 - 3 = 8 numbers less than 660 are divisible by 5 and 11 but not 3,.
The numbers that are divisible by both 3 and 5 have to be a factor of 15. That leaves 15, 30, 45, 60, 75, and 90. There are 6 numbers less than 100 divisible by 3 and 5
