Question

-5,3+(-5,4)+5,3+(-3,7)+4,5

Answer 1

-15,2

-5,3+(-5,4)=-10,7

5,3+(-3,7)=-9

-10,7+-9=-19,7

-19,7+4,5=-15,2

Answer 2

(-5,4)+(-3,7)+4,5=-5,4-3,7+4,5=-4,6

Если переводить в обыкновенную дробь:

$- \frac{23}{5} = - 4\times \frac{3}{5}$

Answer 3

To calculate the expression:

-5.3 + (-5.4) + 5.3 + (-3.7) + 4.5

You can add and subtract the numbers:

(-5.3 + 5.3) + (-5.4 - 3.7) + 4.5

Now, calculate each part separately:

0 + (-9.1) + 4.5

Now, add the two results:

-9.1 + 4.5 = -4.6

So, the final result of the expression is -4.6.
