find the least common denominator (lcd) for the fractions. 1/12 and 3/4 a. 12 b. 4 c. 16 d. 48

'12' and '48' (choices 'A' and 'D') will both work as common denominators.

The least one is '12' .

Since 4 is a factor of 12, any multiple of 12 is also a multiple of 4 , and can
serve as a common denominator.  The smallest multiple of 12 is 12 itself.

1/12
Multiples of 12: 12, 24, 36, 48, 60...

3/4
Multiples of 4: 4, 8, 12, 16, 20, ...

12 is a multiple of both 12 and 4, therefore that will be the LCD.

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!
