Question

1/3+4/5 можно не кратко, а полностью

Answer 1

1/3 + 4/5 =
Приведем дроби к общему знаменателю: 15
Первую дробь умножим на 5 (и числитель, и знаменатель)
Вторую умножим на 3
5/15 + 12/15
Теперь, когда дроби имеют общий знаменатель, складываем
5/15 + 12/15 = 17/15 = 1 2/15

Answer 2

$\frac{1}{3} + \frac{4}{5} = \frac{5 +12 }{15} = \frac{17}{15} = 1 \frac{2}{15}$

Answer 3
