Question

-5.7-(-1.3)=-7.5-(-2.1)=

Answer 1

-5.7-(-1.3)=
= -5.7 + 1.3=
= - 4,4

-7.5-(-2.1)=
= -7.5 + 2.1 =
= - 5,4

---------------------------------

Answer 2

Let's break down the calculations step by step:

1. -5.7 - (-1.3) = -5.7 + 1.3 (Since subtracting a negative is the same as adding the positive) = -4.4

2. -7.5 - (-2.1) = -7.5 + 2.1 (Again, subtracting a negative is the same as adding the positive) = -5.4

So, the results are:

-5.7 - (-1.3) = -4.4 -7.5 - (-2.1) = -5.4

Answer 3

Let's solve this step by step:

1. First, calculate -5.7 - (-1.3): -5.7 - (-1.3) = -5.7 + 1.3 = -4.4

2. Next, calculate -7.5 - (-2.1): -7.5 - (-2.1) = -7.5 + 2.1 = -5.4

So, the results are: -5.7 - (-1.3) = -4.4 -7.5 - (-2.1) = -5.4
