А) 2 целых 5/6 - 1 целая 5/12
To solve this expression, we need to subtract the second mixed number from the first mixed number. Let's break it down step by step:
First, let's convert the mixed numbers into improper fractions: - 2 целых 5/6 can be written as (2 * 6 + 5)/6 = 17/6. - 1 целая 5/12 can be written as (1 * 12 + 5)/12 = 17/12.
Now, we can subtract the second fraction from the first fraction: 17/6 - 17/12.
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 12. Let's find the equivalent fractions with a common denominator of 12:
17/6 = (17 * 2)/(6 * 2) = 34/12.
Now, we can subtract the fractions: 34/12 - 17/12 = (34 - 17)/12 = 17/12.
Therefore, the result of the expression 2 целых 5/6 - 1 целая 5/12 is 17/12.
Б) 4 целых - 1 целая 2/3
To solve this expression, we need to subtract the second mixed number from the first mixed number. Let's break it down step by step:
First, let's convert the mixed numbers into improper fractions: - 4 целых can be written as 4. - 1 целая 2/3 can be written as (1 * 3 + 2)/3 = 5/3.
Now, we can subtract the second fraction from the first fraction: 4 - 5/3.
To subtract a whole number from a fraction, we need to convert the whole number into a fraction with the same denominator as the fraction. In this case, the denominator is 3:
4 = 4/1.
Now, we can subtract the fractions: 4/1 - 5/3.
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 3. Let's find the equivalent fractions with a common denominator of 3:
4/1 = (4 * 3)/(1 * 3) = 12/3.
Now, we can subtract the fractions: 12/3 - 5/3 = (12 - 5)/3 = 7/3.
Therefore, the result of the expression 4 целых - 1 целая 2/3 is 7/3.
В) 3 целых 2/7 - 6/7
To solve this expression, we need to subtract the second fraction from the first mixed number. Let's break it down step by step:
First, let's convert the mixed number into an improper fraction: - 3 целых 2/7 can be written as (3 * 7 + 2)/7 = 23/7.
Now, we can subtract the second fraction from the first fraction: 23/7 - 6/7.
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 7. Since both fractions already have the same denominator, we can subtract the numerators directly:
23/7 - 6/7 = (23 - 6)/7 = 17/7.
Therefore, the result of the expression 3 целых 2/7 - 6/7 is 17/7.
I hope this helps! Let me know if you have any further questions.
