Why are all 6- digit Fredholl numbers composite?

Answers

Answer 1

Answer: If we have a 6 -digit fredholl number, all numbers must consist of 3 occurrences of digits A, and 3 occurrences of digits B.
So a sum of their digits is 3a+3b
3a+3b=3(a+b) and this number is divisible by 3,
Therefore any 6-digit fredholl number is divisible by 3.
If a number is divisible by any other number than 1 and itself, we call that number a composite number.

3. Ron used 24 cubes to make this 3-step staircase. If he uses a total of 84 cubes to make a similar staircase, how many steps will the staircase have?

Answers

Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)

28 steps because 84 divided by 3 equals 28

Answers

Option C is correct, the fraction equivalent to 2/3 is 6/9.

What is Fraction?

A fraction represents a part of a whole.

Given that Kyle drank 2/3 cup of Apple juice.

We have to find the equivalent fractions of 2/3.

When a fraction is reduced to its lowest terms, the numerator and denominator have no common factor other than 1.

2/3 can be reduced to 6/9 by dividing both the numerator and denominator by 3.

2/3×3/3=6/9

2/3 and 6/9 are equivalentfractions because they both represent the same portion or ratio of the whole.

Hence, option C is correct, the fraction equivalent to 2/3 is 6/9.
