Question

1/3+1/5-2/15 решение

Answer 1

1/3+1/5-2/15 нужно привести к общему знаменателю
5/15 + 3/15 - 2/15=8/15 - 2/15 = 6/15 (можно сократить на 3. получается ) = 2/5

Answer 2

1/3+1/5=1/8
2/5-1,8=1/3

Answer 3

To solve the expression 1/3 + 1/5 - 2/15, we need to find a common denominator for the fractions involved. The least common multiple (LCM) of 3, 5, and 15 is 15.

Let's rewrite the fractions with a common denominator of 15:

(1/3) + (1/5) - (2/15) = (5/15) + (3/15) - (2/15)

Now that the fractions have the same denominator, we can combine the numerators:

(5/15) + (3/15) - (2/15) = (5 + 3 - 2) / 15

Simplifying the numerator:

5 + 3 - 2 = 6

Therefore, the expression simplifies to:

6/15

This fraction can be further simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

6/15 = (6 ÷ 3) / (15 ÷ 3) = 2/5

So the solution to the expression 1/3 + 1/5 - 2/15 is 2/5.
