Step-by-step explanation:
you are adding 3 1/4 to 3 1/4 which is 6 2/4 or 6 1/2
or you can multiply 13/4 by 2 to get 26/4 or 13/2 which, again, is 6 1/2
Ответ:
A, C, E
Step-by-step explanation:
- (3/4) = -3/4
A: A is correct because it is the same equation as above.
B: -3/-4
The negatives cancel out each other, so it would just be 3/4, which is not the same as -3/4, so B is incorrect
C: -3/4 is equal to -3/4, so C is correct
D: -(-3/4)
The negative signs cancel each other out, so it equals 3/4. D is incorrect
E: 3/-4 = -3/4, so E is correct
