3+4x=15 4x=15-3 4x=12 x=12/4 x=3 The check is: If x=3 then, 3+ (4 X 3)=15 3+12=15
12 and 15 as fraction is 12/15 . then turn it into simplest form you divide top number ( 12 ) and the bottom number ( 15 ) by the biggest number that fits into both of them which in this case is 3 . now you divide the top number and bottom number by the biggest number that fit into both of them which is 3 . so 12 divided 3 is 4 and 15 divided by 3 is 5 so your final answer is 4/5 . REMEMBER - when simplify fraction , the top and bottom number is always divided by the same number which is the biggest number that fits into both of them .
45/12 = 15/4 = 3 3/4
3 Goes in to of 12 and 15 because 3 times 5 is 15 and 3 times 4 is 12!...So there u go...I hope I answered ir question!....Have a nice day! =)
9
-12
12 + 3 = 15
3+4x=15 4x=15-3 4x=12 x=12/4 x=3 The check is: If x=3 then, 3+ (4 X 3)=15 3+12=15
4n+3 = 15 15 - 3 = 12 4n = 12 12 / 4 = 3 (3 X 4) + 3 = 15
3
Because 3 is the largest number that divides into both 12 and 15 evenly with no remainder.
1 3/12
12.

3, 6, 9, 12, 15.As in the three times table.
45/12 = 15/4 = 3 3/4
