Both 5 and 7 are prime numbers, so the only number that could go into both evenly would be 1.
70
Factor them both. 1 x 5 = 5 1 x 7 = 7 Discard the common factor (1) and combine the remaining ones 5 x 7 = 35 35 is the lowest (least) number that both 5 and 7 will go into evenly.
1, 5, 7, 35.
35 is the LCM of the numbers 7 and 5 because 7 multiplied by 5 is 35 and 35 is the lowest number that both 7 and 5 will go into.List the multiples.5, 10, 15, 20, 25, 30, 35, 407, 14, 21, 28, 35, 4235 is the smallest (least) number that appears on both lists.
To get this answer, you will need to divide both answers by 5 first, because that is the obvious number that will go into both. 385/5= 77 420/5=84 So the new fraction is 77/84. 7 will go into both (it goes into 70, and 70 plus 14(another multiple of 7!) = 84) 77/7=11 84/7=12 385/420 in its simplest form is 11/12!
5, 7, and 3 go into 105.
35/1000 - divide both top and bottom by 5 and you get 7/200, which is in its simplest form
Both numbers add up to 7
the biggest number that can go into both 10 and 35 is 5. so 5 goes into 10, 2 times and 5 goes into 35, 7 times so the answer is 2/7
-12
2/5 (2 over 5) both go into 77. If you have trouble with these, just divide by small numbers first like me, 154 and 385 both go into 7 which make 22 and 55 when divided and they go into 11 making 2 and 5.
