Answer:
1. 8.99 2. -5/2 3. -7/4 4. 1/10
Step-by-step explanation:
Hii, so I look in your profile to find the questions...I'm assuming they were the product ones.
1. -3.1*(-2.9) --> since its double negatives the answer would be a positive, which is 8.99
2. 1 1/2 * (-5/3) --> 1 1/2 can be converted into 3/2, which is a improper fraction.
[tex]\frac{3}{2} * -\frac{5}{3}[/tex] We can then reduce the 3, since they are common factors to [tex]-\frac{1}{2} *5[/tex]
which is [tex]-\frac{5}{2}[/tex], can also reduce to -2.5
3. -3 1/2 *.5. once again reduce and simplify.
-7/2 * 1/2 ... then like terms =-7/4
4. -4/5 * -1/8, you can reduce to 1/5 * 1/2, then multiply fraction to get 1/10
