Answer:
The correct answer would be B! -7
The answer to this equation is
x=15
One way is to find the prime factorization for the denominators which are 3 and 4. The prime factorization of 3 would be 1 x 3 and 4 would be 2 x 2. Since we only use prime numbers to find the prime factorization we would have 2 x 2 x 3 = 12 which give us the the least common denominator for 2/3 and 3/4. Final answer is 12.
1g= 0.001 kg
163000 * 0.001 = 163 kg
