24 is the answer. 
You have to list the multiples of your denominators which is 6 and 8 and whichever number is repeated which in this case is 24 would be your lowest common denominator.

24 
you need to multiply and find the least conman factors.then multiply them and simplify if needed.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

The answer would be 27 because assuming that each package has 1 bar of soap and 1 tube of toothpaste, after 27 packages they would run out of toothpaste
