Answer 1

Resposta:

Explicação passoa passo:

Calcule:
a) 18/3 + 9/5
= 6+9/5
= (5.6+9)/5
= (30+9)/5
= 39/5
_________


b)13,03 - 0,03 - 1,2 =

13,03
-0,03
---------
13,00

13,00
-1,20
--------
11,80

R.: 11,80
______

c) (44/3) • (-36/11)
= - 44/3 . 36/11
= -44/11 . 36/3
= - 4.12
= - 48

R.: - 48
_________

d)(7/49) : (8/56)
=​ 7/49 (:7)/(:7) : 8/56
= 1/7 . 56/8
= 1 . 7
= 7

Resp.: 7

Answer 2

Resposta

Explicação passo a passo:

Calcule:
a) 18/3 + 9/5 =
Mmc (3,5)=15
= (5.18+3.9)/15
= (90+27)/15
= 117/15

R.: 117/15
_________

b)13,03 - 0,03 - 1,2 =

= 13,00 - 1,20
= 11,80
R.: 11,80
_________

c) (44/3) • (-36/11) =
= - 44/11 . 36/3
= - 4.12
= - 48

R.: - 48
_________
d)(7/49) : (8/56) =
= 7/49 . 56/8
= 7/49 . 7
= 49/49
= 1

Resp.: 1
