Question

4/10 + 1/3 ???????????​

Answer 1

Ответ: 11/15.

Пошаговое объяснение:

Чтобы сложить дроби с разными знаменателями, нужно привести их к одному знаменателю, сложить числители, а знаменатель оставить прежним. если возможно - сократить полученную дробь.

Поэтому:

1-й способ.

4/10 = 12/30, 1/3 = 10/30,

4/10 + 1/3 = 12/30 + 10/30 = 22/30 = 11/15.

2-й способ.

4/10 = 2/5 = 6/15, 1/3 = 5/15,

4/10 + 1/3 = 6/15 + 5/15 = 11/15.

Answer 2

To add fractions, you need to have a common denominator. In this case, the common denominator is 30. Let's find the equivalent fractions:

4/10 = 12/30 (multiplied numerator and denominator by 3) 1/3 = 10/30 (multiplied numerator and denominator by 10)

Now, you can add the fractions:

12/30 + 10/30 = 22/30

However, this fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

22/30 = (22 ÷ 2) / (30 ÷ 2) = 11/15

So, 4/10 + 1/3 is equal to 11/15.
