25 and 20 will each go into 100.
Both 20 and 25 are divisible by 5 20/25 20/5=4 25/5=5 20/25=4/5
5
what goes into both 21 and 25
5X + 25 = 20 subtract 25 from each side 5X + 25 - 25 = 20 - 25 5X = - 5 divide both side integers by 5 X = - 1 check 5(-1) + 25 = 20 - 5 + 25 = 20 20 = 20 checks
Both 15 and 20 can go into 60, as they are both factors of that number.
25... 400/20 is 20 and 100/20 is 5 so 20+5 is 25...
20 of them
10 = 2 x 525 = 5 x 510 and 25 both go into 5.
Exactly 25 times
25/20. Divide both top and bottom by 5.5/4 or 1 and 1/4
