Find each product by factoring the tens.

-Dominant- [34]

<span>A technique for mental multiplication is called factoring the tens which relies on the fact that 10*n, for any real number n. This will make the problems easy to compute. 6 x 2 = 12 is a memory value. </span>

12 x 10 = 120

12 X 100 = 1200

Take for instance in 6 x 2, 6 x 20 and 6 x 200. Find the factors and these are the computations. We can also say:

It must be remembered that in the commutative and associative properties of multiplication, the order of the factors does not matter when solving this kind of problem

Lloyd is arranging his science project, math project, and art project on his desk. The tree diagram below shows the sample space

Margarita [4]

The tree diagram is constructed and attached below in the image.

First we have to make a choice out of 3 subjects, so the probability of choosing art as the first subject is 1/3.

Once we have chosen art as the first subject, we have two choices. So the probability of choosing each option now is 1/2. Thus, the probability of choosing math, science is 1/2.

The probability of choosing the projects in order of art, math, science = 1/3 x 1/2 = 1/6

Therefore, the probability that the projects are in order of art, math, science is 1/6 (one over 6). So first option gives the correct answer.
