Question

Me ayudan porfi doy coronita
. = x multiplicación
: = % división
(100 + 4) = Si en una situación aparece esto significa, Hacer primero
a) 27 + 3 – 5 + (5 + 2 . 10 =
b) 15 + 25 : 5 + 3 . 10 – 10 =
c) 18 + 4 – 3 + 2 – 6 + 15 + (485.2) =
d) (100 . 2) + 125 – 25 + 20 . 10 =

Answer 1

a)= ((1+3)/9).2/5-2/15

= (4/9.2/5)-2/15

= 8/45-2/15

= (8-6)/45

= 2/45

b) = 2/3-1/6.(54/5-(12/5.9/4))

= 2/3-1/6.(54/5-27/5)

= 2/3-1/6.((54-27)/5)

= 2/3-1/6.(27/5)

= 2/3-27/30

= (20-27)/30

= - 7/30

c) ((15+10)/6)/((5-2)/6)

= (25/6)/(3/6)

= 100/18

= 50/9

d) 5/11.11/4-4/9

= 55/44-4/9

= (45-16)/36

= 29/36
