Question

The number 30 can be written as the product 2⋅15. Come up with three new and distinct ways to express the number 30 as the product of two other numbers.

Answer 1

Answer:

$30 = 2* 5*3 = (2*5) *3 = 10*3=30$

$30 = 2* 5*3 = (2*3) *5 = 6*5 =30$

$30= 1*30 =30$

Step-by-step explanation:

For this case we know the following info:

$30= 2*15$

And we want to find with three new and distinct ways to express the number 30 as the product of two other numbers

First way

We can take the factor of 15 and we got 15 = 5*3

So then we can express the number 30 like this:

$30 = 2* 5*3 = (2*5) *3 = 10*3=30$

Second way

We can take the factor of 15 and we got 15 = 5*3

So then we can express the number 30 like this using the associative commutative property:

$30 = 2* 5*3 = (2*3) *5 = 6*5 =30$

Third way

For this case we can assume that we can discompose the number 30 as the product of 30*1, using the identity property and we have:

$30= 1*30 =30$
