Lemma 2.3.2 (Multiplication is commutative). Let n,m be natural питbers. hen n x m = mхп.

Paraphin [41]

Answer:

Multiplication is commutative.

Step-by-step explanation:

Let n,m be two natural numbers.

We have to show that $n\times m=m\times n$

We will prove this by induction

For n = 1, we have $n\times 1 = 1\times n = n$ , which is true.

Let the given statement be true for n-1 natural numbers, that is,

$(n-1)\times m = m\times (n-1)$

Now, we have to show that it is true for n natural numbers.

$nm = (n-1)m + m = m(n-1) + m$

which is equal to

$(m-1)(n-1) + (n-1) + m$

$= (m-1)(n-1) + (m-1) + n$

$= n(m-1) + n$

$= (m-1)n + n$

$= mn$

Hence, by principal of mathematical induction, the given statement is true for all natural numbers.

A newspaper carrier has $1.80 in change. He has two more quarters than dimes but three times as many nickels as quarters. How ma

Mazyrski [523]

$1\ quarter=\$0.25\\1\ dime=\$0.10\\1\ nickel=\$0.05\\\\q\ \ \ \rightarrow\ \ \ the\ number\ of\ the\ quarters\\d\ \ \ \rightarrow\ \ \ the\ number\ of\ the\ dimes\\n\ \ \ \rightarrow\ \ \ the\ number\ of\ the\ nickels\\\\q=2d\ \ \ and\ \ \ n=3q\ \ \ \Rightarrow\ \ \ n=3\cdot 2d=6d\\\\q\cdot0.25+d\cdot0.10+n\cdot 0.03=1.80\\\\2d\cdot0.25+d\cdot0.1+6d\cdot0.05=1.8\\\\$

$0.5d+0.1d+0.3d=1.8\\\\0.9d=1.8\ \ \ \Rightarrow\ \ \ d=2\ \ \ \Rightarrow\ \ \ q=2\cdot2=4\ \ \ and\ \ \ n=6\cdot2=12\\\\Ans.\ 4\ quarters,\ 2\ dimes,\ 12\ nickels$
