15 more than -3 = 12

3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
4n+3 = 15 15 - 3 = 12 4n = 12 12 / 4 = 3 (3 X 4) + 3 = 15
12 + 3 = 15
10/15 2/3 = 10/15 10/15 = 3/5
No. .3 meters is larger than .15 meters. Just because there are more digits in .15 meters, does not make the number larger.
Five
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
There are more than 3. there are about 15.
15 is more than 2.
-2
9/15 = 3/5 5/25 = 1/5 9/15 is more than 5/25.
Example: Three more than half of a number is 15. >Take the number (24) and divide it in half (or by 2). 24 / 2 = 12 >Take the 12 and add 3 12 + 3 = 15
2, 3 and 5 are prime numbers but 15 is a composite number because it has more than two factors
90 is one such number.
