#6,7 are positive, the rest are negative
Yeahhh...I kept getting negative.
6. –56 ÷ (–7)
A negative divided by a negative must be positive.
7. –7(–2)(2)
14 * 2 = 28
Thank you, Mrs.Sue. Most of my answer were negative...so..I thought that I might have been doing something wrong.
But, they were all right!
To solve these problems by multiplying or dividing integers, you simply perform the operation indicated. Here's how you can get the answer to each question:
1. Multiply -4 by 3: -4(3) = -12. The answer is -12.
2. Divide 27 by -3: 27 ÷ (-3) = -9. The answer is -9.
3. Divide -40 by 8: -40 ÷ 8 = -5. The answer is -5.
4. Multiply 6 by -5: 6(-5) = -30. The answer is -30.
5. Multiply 3 by -3: 3(-3) = -9. The answer is -9.
6. Divide -56 by -7: -56 ÷ (-7) = 8. The answer is 8.
7. Multiply -7 by -2 and then by 2: -7(-2)(2) = 28. The answer is 28.
8. Divide 18 by -2: 18 ÷ (-2) = -9. The answer is -9.
So the answers are:
1. -12
2. -9
3. -5
4. -30
5. -9
6. 8
7. 28
8. -9
