Answer 2

Answer:

-1  1/88

Step-by-step explanation:

-3/8 - 7/11

LCM of 8 and 11 = 88

Therefore, to make -3/8 denominator 88, we have to multiply numerator and denominator by 11.

-3*11/8*11 = -33/88

To make 7/11 denominator 88, we have to multiply numerator and denominator by 8.

7*8/11*8 = 56/88

Therefore the question is now,

-33/88 - 56/88

Use the rule = a/m - b/m = (a-b)/m

Therefore, (-33-56)/88

= -89/88

= -1  1/88
