Question

Признаки делимости на 10, на 5,и на 2 из чисел 48,470,2473,5625,378,8480,8305,932,945,580600 выпишите те,которые делятся нацело : 1) на 2; 2) на 5; 3) на 10. умоляю,очень надо​

Answer 1

Ответ:

если число четное то оно делится на 2 (если число оканчивается на 0 2 4 6 8 то оно четное)

если число оканчивается на 0 или 5 то оно делится на 5

если число оканчивается на 0 то оно делится на 10

Answer 2

Divisibility Tests for 10, 5, and 2

To determine if a number is divisible by 10, 5, or 2, we can use specific divisibility tests. Let's apply these tests to the given numbers: 48, 470, 2473, 5625, 378, 8480, 8305, 932, 945, and 580600.

1) Divisibility by 2: - A number is divisible by 2 if its last digit is even (0, 2, 4, 6, or 8). - Numbers divisible by 2: 48, 470, 5625, 378, 8480, 932, and 580600 [[1]].

2) Divisibility by 5: - A number is divisible by 5 if its last digit is either 0 or 5. - Numbers divisible by 5: 470, 5625, 945, and 580600 [[2]].

3) Divisibility by 10: - A number is divisible by 10 if it ends with a 0. - Numbers divisible by 10: 470, 5625, 8480, 932, 945, and 580600 [[3]].

In summary, the numbers that are divisible by: - 2: 48, 470, 5625, 378, 8480, 932, and 580600. - 5: 470, 5625, 945, and 580600. - 10: 470, 5625, 8480, 932, 945, and 580600.
