Question

ajutor urgent e pe viata si moarte

Answer 1

Răspuns:

$- 4 \frac{1}{3} = - \frac{4 \times 3 + 1}{3} = - \frac{13}{3}$

$0.3 = \frac{3}{10}$

$1.(3) = 1 \frac{3}{9} = 1 \frac{1}{3} = \frac{4}{3}$

Explicație pas cu pas:

$- \frac{13}{3} - \frac{3}{10} + \frac{4}{3} = - 3 - \frac{3}{10} = - \frac{33}{10} = - 3.3$

Answer 2

Răspuns:

Explicație pas cu pas:

0,3=3/10

1,(3) = (13-1)/9= 12⁽³/9⁽³=4/3

-4¹/₃=- (4*3+1)/3=-13/3

=  -¹⁰⁾13/3-³⁾3/10+¹⁰⁾4/3

= -130/30-9/30+40/30

= - 139/30+40/30

= -99⁽³/30⁽³

= - 33/10

= -3,3
