25 can go into 40 once because 25 is smaller than 40. When you divide 40 by 25, you get 1 with a remainder of 15. This means that 25 can fit into 40 one time completely, with 15 left over.
-15
The interval is [15, 40].
65
55
It is: 15+25 = 40
Once - with a remainder of 15.
Thw two numbers are 25 and 15 because 25+15 = 40 and 25-15 = 10
(-25 + -70 + 15 + -31 + -25 + 40)/6 = -16
15 is 40% less than 25.
15 is 40% less than 25.
The LCM is 600.
