Qual é o maior divisor de 246 que é menor que 20?

12

Step-by-step explanation:

here is the answer in English

12 = 22 × 3;

246 = 2 × 3 × 41;

Multiply all the common prime factors, by the lowest exponents.

Greatest (highest) common factor (divisor):

gcf, hcf, gcd (12; 246) = 2 × 3

here is the answer in Spanish

12 = 22 × 3;

246 = 2 × 3 × 41;

Multiplica todos los factores primos comunes, por los exponentes más bajos.

Máximo común divisor:

mcd (12; 246) = 2 × 3

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
