Let d = -3
-d
-(-3)
Answer: 3
I think it is 1156 because 345 + 425 = 770, and 770 + 386 = 1156
1/6 - 6,12,18,24 (we counted by 6's, 2 times to get 12)
1/4 - 4,8,12,16 (we counted by 4's, 3 times to get 12)
12 is the LCD (Lowest Common Denominator) of the 2 fractions
*Now that we have the denominator, we need to find the numerator
1/12 - 1x2 (why 2? well because we had to count by 6's, 2 times to get 12)
1/4 - 1x3 (why 3? well because we had to count my 4's, 3 times to get 12)
2/12 and 3/12 is the answer
I hope you get it!!
