6 Listen to and read the dialogue to find out if Luke has accepted Eve's invitation.
Eve: Hi, it's Eve here! Have you got any plans
for the weekend?
Luke: No, why?
Eve: We're going to the Activity Centre,
Would you like to come with us?
Luke: Us?
Eve: Yes, my friends Tara and Lee.
Luke: I don't know. You know I don't like meeting new people.
Eve: But you know them, I'm sure. They are in my class. Tara is
tall and thin with long curly hair, often in a ponytail.
Luke: Oh, Tara from the acting group. I know her.
She seems very nice.
Eve: Yes, she is. And Lee is short and thin, easy to
talk to, he plays the violin. He likes music.
Luke: All right then.
Eve: Let's meet in front of the Activity Centre at 10

Какой у тебя вопрос?

НОД (20;48) - это Наибольший Общий Делитель , или самое большое число, на которое можно делить и 20 и 48

Сначала разложим на простые множители 20 и 48 (то есть делим на 2 столько раз, сколько делится, потом на 3, 5, 7, 11, 13 - это простые множители)

20:2=10 10:2=5 5:5 =1 , то есть

20=2*2*5 - это разложение 20 на простые множители, теперь 48

48:2=24 24:2=12 12:2=6 6:2=3 3:3=1, значит

48=2*2*2*2*3

еще раз выпишу разложение на простые множители

20=2*2*5,

48=2*2*2*2*3, теперь выписываем те общие множители, которые есть и у 48 и 20, а общее у них - это по две двойки, значит

2*2 = 4 - это НОД для 20 и 48

НОД(20;48) = 2*2 =4

2. НОД(28;40)= 2*2=4

28=2*2*7

40=2*2*2*5 (общее - 2*2 =4)

Сравниваем

НОД(20;48) = 4 НОД(28;40) = 4

НОД(20;48)=НОД(28;40)
