13. The least common multiple of two non-zero integers a and b is the unique positive integer m such that (i) m is a common mult
Vlad [161]

Answer:

[a,b] divides n

Step-by-step explanation:

Let us denote the least common multiple of a and b [a,b]=m.

We want to prove that m divides n, where n is a multiple of a and b.

We suppose m does not divide n, then by the Division Theorem, there exists q and r integers such that:

(1) ... n=mq+r, where 0<r<m

As n is a multiple of a and b, there exists s and t integers such that:

sa=n and tb=n

Same thing happens to m as it is the least common multiple, there exists u and v such that:

ua=m and vb=m

So (1) has the following form:

n=mq+r ⇒ sa=uaq+r ⇒sa-uaq=r⇒(s-uq)a=r and

n=mq+r ⇒ tb=vbq+r ⇒ tb-vbq=r⇒ (t-vq)b=r

So r is a multiple of a and b, but r<m which is a contradiction as, m is the least common multiple of a and b. So this concludes the proof.

So this means that \frac{ab}{m} is and integer.

As m= vb, then \frac{m}{b} is an integer, lets say \frac{m}{b}=v; and as m=ua, then \frac{m}{a}=u.

So \frac{ab}{m}v=\frac{ab}{m}\frac{m}{b}=a, so \frac{ab}{m} divides a; on the other hand, \frac{ab}{m}u=\frac{ab}{m}\frac{m}{a}=b, so \frac{ab}{m} divides b. From this we can conclude that \frac{ab}{m} is a common divisor of a and b.

Together,two boxes of spices weigh 4 pounds 8 ounces. Each pound is worth $400. How much are the boxes worth in all.
Zanzabum

The total worth of the 4 pounds and 8 ounces of box is $1800

<h3>Total cost</h3>

Weight of the boxes:

  • 4 pounds
  • 8 ounces
  • Cost of each pound = $400

Convert ounces to pounds:

8 ounces to pounds = 0.5 pounds

Total cost of the boxes = 4 pounds (400) + 0.5 pounds (400)

= 1600 + 200

= $1,800

damaskus [11]
We know that

14 days------------> 14*7 hours-----> 98 hours

98 hours*<span>$28 per hour-------> $2744
one paid day-------> </span>$28*7 hours-----> $196<span>

therefore
[</span>her true hourly wage]=[$2744+$196]/(98)-----> $2940/98-----> $30 per hour

the answer is
$30 per hour
