Answer 2

C) 48*(30/60 + 10/60 + 30/60)

= 48* 7/6

=8 x 7

= 56

 

e)

10*(100,5 - 16,1: 1/5)

=10* (100,5 - 161/10 * 5/1)
= 10* (100,5 - 161/2)
=10 * 20

= 200

 

G)

33/4: 15*1000

33/4 * 1/15 * 1000

33/60 * 1000

3300/6
=550

 

H)

1000 - 4/5 :0,8

1000 - 4/5 * 5/4

=1000 - 1

= 999

 

I)

37,1:(4-3,9)

37,1 : 1/10

371/10 + 10/1

= 371

J)

7-4 i 4/5*(17 i 3/5 + 12,4)

= 7 - 4 i 4/5 * 30

= 7 - 24/5 * 30

= 7 - 24 * 6

= 7 - 144

= -137

 

K)

0,232:0,4*100

=232/100 * 10/4 * 100

= 232/10 * 1/4 * 100

= 232/40 * 100

= 2320/4

= 580

 

B) 12000 + 6 i 2/5 * 5 i 5/8

= 12000 + 32/5 * 45/8

= 12000 + 4 * 9

= 12000 + 36

= 12036

C) (500,15 +9): 0,01

= 509,15 * 100

= 50915

 

D)

330 +1 i 3/5 * 60

330 + 8/5 * 60

= 330 + 8 * 12

= 330 + 96

= 426

 

F)

3,6*60-1,3*20

36/10 * 60 - 13/10 * 20

= 216 - 26

= 190
