Question

А)1/10+1//12+1/4=? Б)1/6+1/5-1/3

Answer 1

Это А
В там ответ 1/30
Так решается 5+6-10/30 это равно 1/30

Answer 2

Let's solve the two expressions step by step:

А) 1/10 + 1/12 + 1/4:

Step 1: Find a common denominator for the fractions, which is the least common multiple (LCM) of 10, 12, and 4. The LCM of 10 and 12 is 60, and the LCM of 60 and 4 is 60.

Step 2: Convert each fraction to have a denominator of 60:

1/10 = 6/60 (multiplied numerator and denominator by 6) 1/12 = 5/60 (multiplied numerator and denominator by 5) 1/4 = 15/60 (multiplied numerator and denominator by 15)

Step 3: Add the fractions together:

1/10 + 1/12 + 1/4 = 6/60 + 5/60 + 15/60 = (6 + 5 + 15) / 60 = 26 / 60

Step 4: Simplify the fraction, if possible:

26 / 60 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.

26 / 60 = 13 / 30

So, the result of А) 1/10 + 1/12 + 1/4 is 13/30.

Б) 1/6 + 1/5 - 1/3:

Step 1: Find a common denominator for the fractions, which is the least common multiple (LCM) of 6, 5, and 3. The LCM of 6 and 5 is 30, and the LCM of 30 and 3 is 30.

Step 2: Convert each fraction to have a denominator of 30:

1/6 = 5/30 (multiplied numerator and denominator by 5) 1/5 = 6/30 (multiplied numerator and denominator by 6) 1/3 = 10/30 (multiplied numerator and denominator by 10)

Step 3: Add the fractions together:

1/6 + 1/5 - 1/3 = 5/30 + 6/30 - 10/30 = (5 + 6 - 10) / 30 = 1 / 30

So, the result of Б) 1/6 + 1/5 - 1/3 is 1/30.
