In reality your common denominator should be the Least Common Multiple. The LCM is the product of highest occurring primes of the numbers prime factorizations...
4=2*2, and 12=2*2*3. So the LCM is 2*2*3=12 Now that you know what the least common multiple is we can say that:
(3/4)(3/3)+5/12
9/12+5/12
(9+5)/12
14/12
7/6 which should be converted to a mixed number as this is an improper fraction...
(6+1)/6
1+1/6
1 1/6
8/4 = 2 caps per ball of wool
so 6/2 = 3 balls of wool are needed.
4/8 = x/6
8x/24
x = 24/8 = 3
Times = multiplies so flip that to division
25 divided by 5 = 5
5*5=25
So the answer is $5
An odd number of negative factors will give you a negative.
