Answer:
(-4 1/8)
Explanation:
-6 1/4 - (-2 1/8) The subtraction cancels out the subtraction.
-6 1/4 + 2 1/8
-6 + 2 = -4 The whole numbers are independent in this case.
1/4 + 1/8 Find the least common multiple
Multiples:
4| 4_8_12
8| 8_16
8 is the least common multiple
4 goes into 8 twice so multiply the top and bottom by 2
4 * 2 = 8 1 * 2 = 2
-2/8 + 1/8 = -1/8
add that to -4
