The least common multiple of 3 and 8 is 24.

The least common multiple of two numbers is the lowest value number that is a multiple of both the numbers. To find the least common multiple of 3 and 8, you first list their multiples:

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24...

Multiples of 8: 8, 16, 24, 32, 40, 48, 56...

When you compare the two lists of multiples, you can see that the number 24 is the lowest number that is a multiple of both 3 and 8, so it is their LCM, or least common multiple.

Sean answer 63 questions correctly on a test of 81 questions what fractional part of the question did he answer incorrectly

ElenaW [278]

Answer:

Sean got 63/81 questions right as a fraction.

Step-by-step explanation:

Sean got 63/81 correct. If there was a total of 81 questions, you put that as your denominator.

Now ask yourself: Can you simplify?

Yes you can.

You divide each number from the fraction by 9.

63 / 9 = 7

81 / 9 = 9

7/9 questions that Sean got correct.

If you also want a percentage + grade, Sean would get 77% which would be a C+

What is the 4th term in the sequence b(n)=1(-2)^n-1

mel-nik [20]

$b(n)=1(-2)^n-1$

When n = 4,
$b(4)=1(-2)^4-1$

$b(4)=16-1$

$b(4)=15$

-------------------------------------------------------------

$b(n)=1(-2)^{n-1}$

When n = 4
$b(4)=1(-2)^{4-1}$

$b(4)=1(-2)^3$

$b(4)=1(-8)$

$b(4)=-8$

every sixth visitor to an animal shelter gets a free animal calendar every twentieth visitor gets a free animal toy. Which visit

Akimi4 [234]

Here we have a case of the least common multipl(lcm) of 6 and 20.
Prime numbers 2,3,5,7,11,13,17,19... (natural numbers greater than 1 that has no positive divisors other than 1 and itself) .
lcm(6,20)= 6 20 | 2
                  3 10 | 3
                  1 10 | 2
                       5 | 5
                       1
2*3*2*5=60 The first one to get both calendar and the animal toy will be 60th.

Explenation: First we look for the smallest prime number with wich 6 and 20 can be devided by. That is 2. Next is 3. Since 10 is not divisible by 3, we only copy it. Under the 6 we got 1, wich is our goal. Now we continue to devide 10 by prime numbers till we also get 1. We now multiple all divisors and we get the least common multiple.
