Answer:
6
Step-by-step explanation:
6 is the greatest common factor of 12 and 18
Lnx+5lny-1/2lnz= ln(5x) - ln√z ==> ln[(5x)/√(z)]
So, first, since 21.8 is a whole thing and you need a part, write x/21.8. Then, compare it to 60/100, or 60%. 100/21.8=4.76. So, divide 60/4.76 and your answer is 12.6.
Glad to help.
