Question

А) -2 1/6-(-3). Б) 7 5/8-9 2/8.

Answer 1

Ответ:А) 5/6 , Б)-13/8

Пошаговое объяснение:

А) -2 1/6-(-3)=-13/6+3=18/6-13/6=5/6

Б) 7 5/8-9 2/8=61/8-74/8=-13/8

Answer 2

Let's solve the given mathematical expressions:

A) -2 1/6 - (-3)

To subtract a negative number, we change the subtraction operation to addition and change the sign of the number being subtracted. So the expression becomes:

-2 1/6 + 3

To add these mixed numbers, we need to convert them to improper fractions:

-2 1/6 = -13/6 3 = 18/6

Now we can add the fractions:

-13/6 + 18/6 = (18 - 13)/6 = 5/6

Therefore, the result of -2 1/6 - (-3) is 5/6.

B) 7 5/8 - 9 2/8

First, let's convert these mixed numbers to improper fractions:

7 5/8 = 61/8 9 2/8 = 74/8

Now we can subtract the fractions:

61/8 - 74/8 = (61 - 74)/8 = -13/8

Therefore, the result of 7 5/8 - 9 2/8 is -13/8.
