15. This is not true because it depends on the actual numbers. You could say 20 times .5 - The answer is 10. .5 means 50 percent of out 100 and 10 is equal to 10% of out 100. 50% is greater than 10%.
16. A conjecture is a statement. The product of multiplying two integers with the same sign is positive.
17. This is true because I learned "unlike = unpositive" Different signs = negative. (lol unpositive isn't a word but it helped me in school)
Problems:
1. -5 x - 5 = +25.
2. 5 x 5 = +25 also.
(the plus sign in front of the 25 is just to show that the 25 is a positive and not negative number)
GOOD LUCK!
