<em>Comment on finding the LCM</em>
The LCM can be found several ways. One way is to factor out the greatest common factor (GCF) and write each number in terms of that:
12 = 2×6
10 = 2×5
Then the LCM is the product of the unique factors:
LCM(12, 10) = 2×6×5 = 60
This is equivalent to dividing the product of the two numbers by their GCF:
LCM(12, 10) = 12×10/GCF(12, 10) = 12×10/2 = 60
One can also write each number in terms of its prime factors, then form the product of each of those to its highest power:
12 = 2²×3
10 = 2×5
LCM(12, 10) = 2²×3×5 = 60
Answer:
(-7)(-1.2)=8.4
(7)(-1.2)=-8.4
(2.5)(-2)=-5
(-2 1/2)(2)=5
Step-by-step explanation:
First,a negative multiplied by another negative will have a product that is positive.
Also, -2 1/2 is the same as -2.5
im pretty sure its the fourth choice but its been a while since ive done graphing
