Can you please help me this homework?​
Elina [12.6K]

Answer & Step-by-step explanation:

Working from the inner circle out:

Natural Numbers: <em>1,2,3,4</em>

These are the numbers you would use to count

Whole Numbers:<em> 0,1,2,3</em>

The natural numbers and zero

Integers:<em> -3,-2,-1,0,1,2,3</em>

The natural numbers, their opposites, and zero

Rational Numbers: -\frac{1}{2}, 0.22222222....,1,2,\frac{2}{3}  ,\frac{5}{4} ,6.1

-are all numbers that you can write as a quotient of integers \frac{a}{b}, b\neq  0

-include terminating decimals. For example,  \frac{1}{8}=0.125

-include repeating decimals. For example, \frac{1}{3}=0.333333...

In the rectangle:

Irrational Numbers: \sqrt{2} ,\pi

-have decimal representations that neither terminate nor repeat. For example, \sqrt{2} =1.414213...

-cannot be written as quotients of integers

For each of the following pairs of numbers, find the gcd of the two numbers, and express the gcd as a linear combination of the
Oksana_A [137]

Answer:

a. 14 and 14= (-1)56+1(44)

b. 3 and 3= (-4)60+3(81)

Step-by-step explanation:

Case 1: GCD is the highest common divisor for both numbers without reminder

a. GCD of 56 and 42 = 14

b GCD of 81 and 60 = 3

Case 2: Express GCD as a Linear combination.

a. GCD = 14 which is also the difference between 56 and 42

Therefore

14= (-1)56+1(44) expresses 14 as a linear combination of 56 and 44.

b. GCD=3, we need to look for a multiple of 60 and 81 that their differences would be 3

Therefore the multiples are:

For 60 = 240 (60×4)

For 81 = 243 (81×3)

3= (-4)60+3(81) expresses 3 as a linear combination of 81 and 60
