Find the least common denominator (LCD) for the fractions. 1/12 and 3/4
      A. 12
      B. 4
    C. 16
    D. 48

Answers

Answer 1

Answer: '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.

Answer 2

Answer: 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.

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.A table with 6 columns and 2 rows. The first column, Original System has 2 x minus 2 y equals 6 and 4 x plus 4 y equals 28. The second column, Equivalent System, has 4 x minus 4 y equals 12 and 4 x plus 4 y equals 28. The third column, Sum of equations in Equivalent System, has 8 x equals 40. The fourth column, Solution to System, is blank. The fifth column, New System Using Sum, has 4 x plus 4 y equals 28 and 8 x equals 40. The sixth column, Solution to New System is blank.

Answer:

$(5,2)$

Step-by-step explanation:

$2x-2y=6\n4x+4y=28$

Column 1 :

$2x-2y=6..........(1)\n4x+4y=28........(2)$

Column 2 :

Eqn(1) $*\ 2$

$4x-4y=12\n4x+4y=28$

Column 3 :

Add the equations.

$(4x+4x)-4y+4y=12+28\n8x=40$

Fourth column :

$8x=40\nx=(40)/(8)=5$

Fift column :

$4x+4y=28\n8x=40$

Sixth column :

Substitute $x=5$ .

$4* 5+4y=28\n4y=28-20\n4y=8\ny=2$

Hence solution is $(5,2)$ .
