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

3 1/8 X + 9 11/14

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.
