Question

1-3/2 , -1-3/2 1-(-3/2)

Answer 1

Ответ:

1 - 3/2 = - 1/2

-1 - 3/2 = - 5/2

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

Answer 2

Ответ:

Пошаговое объяснение:

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

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

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

Answer 3

To evaluate the given expressions, let's perform the calculations step by step:

1. 1 - 3/2:

To subtract fractions, you need to have a common denominator. In this case, the common denominator is 2. So, you can rewrite 1 as 2/2:

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

Therefore, 1 - 3/2 is equal to -1/2.

2. -1 - 3/2:

Similar to the previous expression, we need to find a common denominator. In this case, the common denominator is 2. So, you can rewrite -1 as -2/2:

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

Therefore, -1 - 3/2 is equal to -5/2.

3. 1 - (-3/2):

When you subtract a negative number, it is the same as adding the positive equivalent. So, you can rewrite the expression as:

1 + 3/2

To add fractions, you also need a common denominator. The common denominator is 2. So, rewrite 1 as 2/2:

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

Therefore, 1 - (-3/2) is equal to 5/2.
