The preimeter of a stop sign is 100 in what is the length of each side?

The vast majority of English speaking countries use octagonal (eight-sided) stop signs. Therefore, if one side were equal to 100, then the perimeter of the shape would be 100 x 8 = 800. Don't forget to include your unit of measurement - for which, if it is 100, I'm not sure what you would use...


When you are doing between 50 and 100 do you include 50 and 100?

Typically between is exclusive of it's boundaries, i.e., the bounds are not included. i.e., (50, 100) <-- the interval is said to be open Unfortunately, people use it as an inclusive between sometimes depending on context.

What fraction is between 1.2 and 1.205?

To find a fraction between any two numbers, multiply the two numbers and divide by two. This way we can find unlimited numbers / fractions between any two fractions/numbers. The other way to find fractions between any two fractions is to divide and multiply both the numbers by 100, or 1000, and make the denominators same. Then the numbers between the two numerators gives all the numbers/fractions between those two numbers. For example, to find 100 fractions between 1 and 2, multiply and divide 1 and 2 by 100. This gives 100/100 and 200/100. Now the in between fractions are 101/100, 102/100, 103/100 upto 199/100. To find more, either multiply by 1000 instead of 100 to get 999 fractions. Or use any two numbers above and repeat the same process. To find fractions between 1.2 and 1.205, multiply and divide both numbers by 10000 This gives 12000/10000, 12050/10000. So the in between fractions are 12001/10000, 12002/10000 and so on till 12049/10000. Convert them to decimal.
