Question

What is the result when 1/8x - 2 5/7 is subtracted from 3 1/4x + 7 1/14?

A. 3 1/8x + 9 11/14
B. 3 1/8 + 4 5/14
C.-3 1/8x - 4 5/14
D.-3 1/8x - 9 11/14

Answer 1

Answer:

3  1/8 X   + 9  11/14

Step-by-step explanation:

I'd suggest you group the x terms together and the constants together separately:

 3  1/4 x  +  7  1/14

-(  [1/8]x    -  2  5/7 )   which becomes;

 3  1/4 x  +  7  1/14

  - [1/8]x    +  2  5/7 )

-------------------------------

  3  1/8 X   + 9  11/14     In the column of constants, the LCD is 14.
