Question

Решите пожалуйста 1) (7/12+1/8)-1/12 2) (1/6+7/15)-2/15

Answer 1

Держи, это не так уж и сложно

Answer 2

First, let's find a common denominator for the fractions inside the parentheses:

7/12 + 1/8 = (72)/(122) + 1/8 = 14/24 + 3/24 = 17/24

So, the expression inside the parentheses simplifies to:

(17/24) - (1/12)

To subtract fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 24 and 12 is 24. So, we can write:

(17/24) - (1/12) = (17/24) - (2/24) = 15/24

Therefore, the solution to (7/12+1/8)-1/12 is 15/24.

Let's find a common denominator for the fractions inside the parentheses:

1/6 + 7/15 = 5/30 + 14/30 = 19/30

So, the expression inside the parentheses simplifies to:

(19/30) - (2/15)

To subtract fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 30 and 15 is 30. So, we can write:

(19/30) - (2/15) = (19/30) - (4/30) = 15/30

Therefore, the solution to (1/6+7/15)-2/15 is 15/30, which can be simplified to 1/2.
