Question

-5 - (-2 1/3); 1/6 - (+3)выполните вычитание

Answer 1

-5-(-21/3)= -5-(-7)= -5+7=2

1/6-(+3)=6-3=3

Answer 2

Let's perform the subtractions:

1. -5 - (-2 1/3):

To subtract a negative number, we change the subtraction to addition and invert the sign of the number being subtracted. So, -2 1/3 becomes +2 1/3.

-5 - (-2 1/3) = -5 + 2 1/3

Now, we need to find a common denominator for -5 and 2 1/3, which is 3. So, we can rewrite -5 as -15/3.

-5 + 2 1/3 = -15/3 + 2 1/3

Now, add the whole numbers and fractions separately:

-15/3 + 2/3 = (-15 + 2)/3 = -13/3

So, -5 - (-2 1/3) = -13/3.

2. 1/6 - (+3):

Since +3 is just 3, we can rewrite the subtraction as:

1/6 - 3

To subtract fractions, they need to have a common denominator. In this case, the common denominator is 6.

1/6 - 3 = 1/6 - 18/6

Now, subtract the fractions:

1/6 - 18/6 = (1 - 18)/6 = -17/6

So, 1/6 - (+3) = -17/6.
