Question

what is between of 50 and 70 is divisible by 3?

Answer 1

51 = 3*17
now count by 3's to list the other possibilities

Answer 2

if u r counting the multipules of a number in a larger range, i think u could do this. if you're finding how many multiples of x is in between y and z

first find the smallest number that's divisible by x that's greater than the smaller number, y. let's say this number is a

then find the greatest number that's divisible by x that's less than the bigger number, z. let's say this number is b

divide both a and b by x

last, count how many numbers in between a and b. basically ( b - a )+1

Answer 3

if y and/or z are divisible by x, then just add them in after
