Answer:
1. d 2. a 3. d 4. a 5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.
Answer:
11 1/9 - 3 2/3 = 7 3/9
Step-by-step explanation:
First you have to turn 2/3 into ninths which would be 6/9. Then you have to turn 1/9 into 10/9 by giving one whole and turning it into a fraction. Then you have to subtract 10/9 - 6/9 = 3/9. Finally you have to subtract the wholes 10-3= 7 then your answer would be 7 3/9
Because 5/15 is not a simplified fraction, seeing that its numerator and denominator both have a common factor, you can simplify it to find an equivalent fraction. To do this, divide 5 from the numerator and denominator and then you would get a result of 1/3.
