Answer 1

А) = 5/6
б) = 11/12
в) = 7/8
г) = 5/6 
д) = 2  1/30 ( 2 целых одна тридцатая)

Все числа дробные

Answer 2

Let's solve each of the given subtraction problems step by step:

A) 1 1/2 - 2/3: To subtract fractions, we need to have a common denominator. In this case, the least common denominator (LCD) is 6. We'll convert both fractions to have a denominator of 6.

1 1/2 = 3/2 (since 1 is equivalent to 2/2) 2/3 = 4/6 (multiplied numerator and denominator by 2)

Now, subtract the fractions: 3/2 - 4/6 = (9/6) - (4/6) = 5/6

So, the result of 1 1/2 - 2/3 is 5/6.

B) 1 1/4 - 1/3: Again, we need a common denominator, which is 12 in this case.

1 1/4 = 5/4 (since 1 is equivalent to 4/4) 1/3 = 4/12 (multiplied numerator and denominator by 4)

Now, subtract the fractions: 5/4 - 4/12 = (15/12) - (4/12) = 11/12

Therefore, 1 1/4 - 1/3 equals 11/12.

G) 1 2/3 - 5/6: For this problem, we'll find the common denominator of 6.

1 2/3 = 5/3 (since 1 is equivalent to 3/3) 5/6 = 5/6 (no need to convert)

Now, subtract the fractions: 5/3 - 5/6 = (10/6) - (5/6) = 5/6

Hence, 1 2/3 - 5/6 equals 5/6.

D) 2 3/10 - 4/15: To subtract these fractions, we'll find the common denominator, which is 30.

2 3/10 = 23/10 (since 2 is equivalent to 20/10) 4/15 = 8/30 (multiplied numerator and denominator by 2)

Now, subtract the fractions: 23/10 - 8/30 = (69/30) - (8/30) = 61/30

Thus, 2 3/10 - 4/15 equals 61/30.

E) 3 1/4 - 5/6: To subtract these fractions, we'll find the common denominator of 12.

3 1/4 = 13/4 (since 3 is equivalent to 12/4) 5/6 = 10/12 (multiplied numerator and denominator by 2)

Now, subtract the fractions: 13/4 - 10/12 = (39/12) - (10/12) = 29/12

Therefore, 3 1/4 - 5/6 equals 29/12.

To summarize: A) 1 1/2 - 2/3 = 5/6 B) 1 1/4 - 1/3 = 11/12 G) 1 2/3 - 5/6 = 5/6 D) 2 3/10 - 4/15 = 61/30 E) 3 1/4 - 5/6 = 29/12
