Answer:
<em>LCM</em> = 
Step-by-step explanation:
Making factors of 
Taking
common:

Using <em>factorization</em> method:

Now, Making factors of 
Taking
common:

Using <em>factorization</em> method:

The underlined parts show the Highest Common Factor(HCF).
i.e. <em>HCF</em> is
.
We know the relation between <em>LCM, HCF</em> of the two numbers <em>'p' , 'q'</em> and the <em>numbers</em> themselves as:

Using equations <em>(1)</em> and <em>(2)</em>:

Hence, <em>LCM</em> = 
Answer: R2280
Step-by-step explanation:
Total crates = 10
Bottles in one crate = 12
Total bottles = 10 x 12 = 120
Price of 1 bottle = R19
Price of 120 bottles = R19 x 120 = R2280
A aaaaaaaaaaaaaaaaaaaaaaaaaa
A) 144 degrees since it would be 72 x 2 I think
