Answer 2

Answer:a:c=7:28/3Step-by-step explanation:a:c=3:4There fore, 4a=3c........................Ab:c=6:7Therefore, 7b=6c..........................BBy multiplying both sides of A by 2, we get 8a=6c Substituting this in B, we get 7b=8aLCM of 7&8 is 56Therefore, a=7&b=8 (7×8=8×7)Substituting the value of a in A, we get the value of C. 4×7=3cTherefore, C=28/3.Thus, the answer is a:c=7:28/3
