Luis brings 79 pencils to school after he is each of his 15 classmates an equal number of pencils he will give any leftover pencils to his teacher how many pencils will lose teachers will see and if Luis decides to take an equal share the pencils along with his classmates will his teacher receive more pencils are fewer of pencils so you're thinking

Answers

15*5=75
79-75=4
If Luis gives each of his classmates 5 pencils each, he will have 4 leftover to give to his teacher

16*4=64
79-64=15
If Luis gives himself AND each of his classmates 4 pencils each, he will have 15 leftover to give to his teacher

So... If Luis decides to take an equal share of pencils along with his classmates, his teacher will receive more pencils.

Answer:

It is clear that the multiplication of two values in Eq A is done to get the LCM while same method is not applied for eq B .

Step-by-step explanation:

Given as :

The two statement are

A) The LCM of 5 , 13 = 65

Here The multiple of 5 = 1 × 5

And The multiple of 13 =  1 × 13

So, Applying prime factor method,

least common multiple = product of height power of all factors that occur in resolution

So, LCM = 1 × 5 × 1 × 13

i.e LCM = 65

Again

B) The LCM of 6 , 8 = 24

Here The multiple of 6 = 1 × 2 × 3

And The multiple of 8 =  1 × 2 × 2 × 2

i.e  The multiple of 8 =  1 × 2³

So, Applying prime factor method,

least common multiple = product of height power of all factors that occur in resolution

So, LCM = 2³ × 3

i.e LCM = 24

Hence, It is clear that the multiplication of two values in Eq A is done to get the LCM while same method is not applied for eq B . Answer
