Question

-1/4-1/3= 2,6-(-0,2)=

Answer 1

-1/4-1/3=-3/12-4/12=-7/12
2,6-(-0,2)=2,8

Answer 2

Let's solve the expressions step by step:

1. -1/4 - 1/3: To perform this calculation, we need to find a common denominator for both fractions. The common denominator for 4 and 3 is 12.

-1/4 = -3/12 (multiply numerator and denominator by 3) -1/3 = -4/12 (multiply numerator and denominator by 4)

Now, we can combine the fractions:

-3/12 - 4/12 = (-3 - 4) / 12 = -7/12

So, -1/4 - 1/3 = -7/12.

2. 2.6 - (-0.2): To subtract a negative number, we can change the subtraction to addition by changing the sign of the negative number. So, -(-0.2) becomes +0.2.

Now, we can perform the addition:

2.6 + 0.2 = 2.8

So, 2.6 - (-0.2) = 2.8.
